iPod is a popular brand of portable media players designed and marketed by Apple Inc. and launched on October 23, 2001. As of 2008, the product line-up includes the hard drive-based iPod Classic, the touchscreen iPod Touch, the video-capable iPod Nano, the screenless iPod Shuffle and the iPhone. Former products include the compact iPod Mini and the spin-off iPod Photo (since reintegrated into the main iPod Classic line). iPod Classic models store media on an internal hard drive, while all other models use flash memory to enable their smaller size (the discontinued Mini used a Microdrive miniature hard drive). As with many other digital music players, iPods, excluding the iPod Touch, can also serve as external data storage devices. Storage capacity varies by model.

Apple's iTunes software can be used to transfer music to the devices from computers using certain versions of Apple Macintosh and Microsoft Windows operating systems. [cite web | url=http://www.apple.com/itunes/download/ | title=iTunes system requirements.

Apple focused its development on the iPod line's unique user interface and its ease of use, rather than on technical capability. As of September 2007, more than 150 million iPods had been sold worldwide, making it the best-selling digital audio player series in history.

History and design

iPod came from Apple's "digital hub" category,Kahney, Leander. [http://www.wired.com/news/columns/cultofmac/0,71956-0.html Straight Dope on the iPod's Birth] , "Wired News", 2006-10-17. Retrieved on 2006-10-30.] when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players "big and clunky or small and useless" with user interfaces that were "unbelievably awful," so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple's hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, [" [http://www.designnews.com/article/CA6478178.html 2007 Engineer of the Year Finalist Michael Dhuey’s Hardware Knowledge Helps Breathe Life Into iPod, TelePresence] ", "Design News", 24 September 2007.] and design engineer Jonathan Ive. The product was developed in less than one year and unveiled on 23 October 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put "1,000 songs in your pocket."

Uncharacteristically, Apple did not develop the iPod software entirely in-house, instead using PortalPlayer's reference platform based on 2 ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software's look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sans — a font similar to Apple's corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal in the lock interface. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).

In September 2007, during the course of a lawsuit with patent holding company Burst.com, Apple drew attention to a patent for a similar device that was developed in 1979. Kane Kramer patented the idea of a "plastic music box" in 1979, which he called the IXI.Boffey, Daniel [http://www.dailymail.co.uk/news/article-1053152/Apple-admit-Briton-DID-invent-iPod-hes-getting-money.html Apple admit Briton DID invent iPod, but he's still not getting any money] "Daily Mail", 2008-09-08. Retrieved on 2008-09-08.] He was unable to secure funding to renew the $120,000 worldwide patent, so it lapsed and Kramer never profited from his idea. Kramer is now in talks with the company to discuss how he will be reimbursed.

Trademark

The name "iPod" was proposed by Vinnie Chieco, a freelance copywriter, who (with others) was called by Apple to figure out how to introduce the new player to the public. After Chieco saw a prototype, he thought of the movie "" and the phrase "Open the pod bay door, Hal!", which refers to the white EVA Pods of the Discovery One spaceship. Apple researched the trademark and found that it was already in use. Joseph N. Grasso of New Jersey had originally listed an "iPod" trademark with the U.S. Patent and Trademark Office in July 2000 for Internet kiosks. The first iPod kiosks had been demonstrated to the public in New Jersey in March 1998, and commercial use began in January 2000, but had apparently been discontinued by 2001. The trademark was registered by the USPTO in November 2003, and Grasso assigned it to Apple Computer, Inc. in 2005. [Serial No. 78018061, Registration No. 2781793, records of the U.S. Patent and Trademark Office. InPub, LLC, filed an "IPOD" trademark on 1 June 1999, for "computer software and hardware." The trademark was abandoned 18 May 2000, without commercial use.]

oftware

The iPod line can play several audio file formats including MP3, AAC/M4A, Protected AAC, AIFF, WAV, Audible audiobook, and Apple Lossless. The iPod Photo introduced the ability to display JPEG, BMP, GIF, TIFF, and PNG image file formats. Fifth and sixth generation iPod Classics, as well as third generation iPod Nanos, can additionally play MPEG-4 (H.264/MPEG-4 AVC) and QuickTime video formats, with restrictions on video dimensions, encoding techniques and data-rates. [ [http://www.apple.com/ipodclassic/specs.html iPod Classic Technical Specs] ] Originally, iPod software only worked with Mac OS; iPod software for Microsoft Windows was launched with the second generation model. [ [http://www.apple.com/itunes/download/ iTunes Downloads] ] Unlike most other media players, Apple does not support Microsoft's WMA audio format — but a converter for WMA files without Digital Rights Management (DRM) is provided with the Windows version of iTunes. MIDI files also cannot be played, but can be converted to audio files using the "Advanced" menu in iTunes. Alternative open-source audio formats, such as Ogg Vorbis and FLAC, are not supported without installing custom firmware onto an iPod (e.g. Rockbox).

During installation, an iPod is associated with one host computer. Each time an iPod connects to its host computer, iTunes can synchronize entire music libraries or music playlists either automatically or manually. Song ratings can be set on an iPod and synchronized later to the iTunes library, and vice versa. A user can access, play, and add music on a second computer if an iPod is set to manual and not automatic sync, but anything added or edited will be reversed upon connecting and syncing with the main computer and its library. If a user wishes to automatically sync music with another computer, an iPod's library will be entirely wiped and replaced with the other computer's library.

User interface

iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods (except shuffle and touch) have five buttons and the later generations have the buttons integrated into the click wheel — an innovation that gives an uncluttered, minimalist interface. The buttons perform basic functions such as play, next track, etc. Other operations such as scrolling through menu items and controlling the volume are performed by using the click wheel in a rotational manner. The iPod Shuffle does not have a click wheel and instead has five buttons positioned differently from the larger models. The iPod Touch uses no buttons for any of these functions, instead relying on a multi-touch input style similar to that of the iPhone.

iTunes Store

The iTunes Store is an online media store run by Apple and accessed via iTunes. It was introduced on 29 April 2003 and it sells individual songs, with typical prices being US $0.99, AU $1.69 (inc. GST), NZ $1.79 (inc. GST), €0.99 (inc. VAT), or £0.79 (inc. VAT) per song. Since no other portable player supports the DRM used, only iPods can play protected content from the iTunes Store. The store became the market leader soon after its launch [ [http://www.apple.com/pr/library/2004/aug/10itms.html iTunes Music Store Catalog Tops One Million Songs] , "Apple Inc.", 2004-08-10. Retrieved on 2006-12-28.] and Apple announced the sale of videos through the store on 12 October 2005. Full-length movies became available on 12 September 2006. [Scott-Joynt, Jeremy. [http://news.bbc.co.uk/1/hi/business/5339470.stm Apple targets TV and film market] , "BBC News", 2006-09-12. Retrieved on 2006-09-12.]

Purchased audio files use the AAC format with added encryption. The encryption is based on the FairPlay DRM system. Up to five authorized computers and an unlimited number of iPods can play the files. Burning the files onto an audio CD, then re-compressing can create music files without the DRM, although this results in reduced quality. The DRM can also be removed using third-party software. However, in a deal with Apple, EMI began selling DRM-free, higher-quality songs on the iTunes Stores, in a category called "iTunes Plus." While individual songs were made available at a cost of US$1.29, 30¢ more than the cost of a regular DRM song, entire albums were available for the same price, US$9.99, as DRM encoded albums. On 17 October 2007, Apple lowered the cost of individual iTunes Plus songs to US$0.99 per song, the same as DRM encoded tracks.

iPods cannot play music files from competing music stores that use rival-DRM technologies like Microsoft's protected WMA or RealNetworks' Helix DRM. Example stores include Napster and MSN Music. RealNetworks claims that Apple is creating problems for itself [Kanellos, Michael. [http://news.com.com/2100-1025_3-5177914.html Real's Glaser exhorts Apple to open iPod] , "CNet News", 2004-03-23. Retrieved on 2006-06-20.] by using FairPlay to lock users into using the iTunes Store. Steve Jobs has stated that Apple makes little profit from song sales, although Apple uses the store to promote iPod sales. [Orlowski, Andrew. [http://www.theregister.co.uk/2003/11/07/your_99c_belong/ Your 99c belong to the RIAA – Steve Jobs] , "The Register", 2003-11-07. Retrieved on 2006-06-20.] However, iPods can also play music files from online stores that do not use DRM, such as eMusic or Amie Street.

Universal Music Group decided not to renew their contract with the iTunes Music Store on 3 July 2007. Universal will now supply iTunes in an 'at will' capacity. [Evans, Jonny. [http://www.macworld.co.uk/ipod-itunes/news/index.cfm?newsid=18459 Universal confirms iTunes contract change] , "Macworld UK", 2007-07-04. Retrieved on 2007-07-05.]

Apple debuted the iTunes Wi-Fi Music Store on 5 September 2007, in its Media Event entitled "The Beat Goes On..." This service allows users to access the Music Store from either an iPhone or an iPod Touch and download songs directly to the device that can be synced to the user's iTunes Library.

File storage and transfer

All iPods except for the iPod Touch can function in "disk mode" as mass storage devices to store data files [ [http://docs.info.apple.com/article.html?artnum=306414 iPod touch: Appears in iTunes but not in Finder or Windows Desktop ] ] . If an iPod is formatted on a Mac OS X computer it uses the HFS+ file system format, which allows it to serve as a boot disk for a Mac computer. [ [http://lifehacker.com/software/how-to/boot-up-your-mac-from-your-ipod-260157.php How To: Boot up your Mac from your iPod ] ] If it is formatted on Windows, the FAT32 format is used. With the advent of the Windows-compatible iPod, the default file system used on the iPod line switched from HFS+ to FAT32, although it can be reformatted to either filesystem (excluding the iPod shuffle which is strictly FAT32). Generally, if a new iPod (excluding the iPod Shuffle) is initially plugged into a computer running Windows, it will be formatted with FAT32, and if initially plugged into a Mac running Mac OS X it will be formatted with HFS+.

Unlike many other MP3 players, simply copying audio or video files to the drive with a typical file management application will not allow an iPod to properly access them. The user must use software that has been specifically designed to transfer media files to iPods, so that the files are playable and viewable. Aside from iTunes, several alternative third-party applications are available on a number of different platforms.

iTunes 7 and above can transfer purchased media of the iTunes Store from an iPod to a computer, provided that the DRM media is transferred to any of the five computers allowed for authorization with DRM media.

Media files are stored on an iPod in a hidden folder, together with a proprietary database file. The hidden content can be accessed on the host operating system by enabling hidden files to be shown. The audio can then be recovered manually by dragging the files or folders onto the iTunes Library or by using third-party software.

Equalizer

If the sound is enhanced with the iPods software's equalizer (EQ), some EQ settings — like R&B, Rock, Acoustic, and Bass Booster — can cause bass distortion too easily. [Kuzmanoski, Brian. [http://www.dapreview.net/content.php?article.133 Analysis of the iPod's equalizer] , "DAP review". Retrieved on 2007-02-17.] [ [http://www.macintouch.com/ipod14.html MacInTouch reader report of iPod sound distortion] , "MacInTouch", July 2002. Retrieved on 2007-02-17.] The equalizer amplifies the digital audio level beyond the software's limit, causing distortion (clipping) on songs that have a bass drum or use a bassy instrument, even when the amplifier level is low.Fact|date=March 2008 One possible workaround is to reduce the volume level of the songs by modifying the audio files.Fact|date=March 2008

Hardware

Connectivity

Originally, a FireWire connection to the host computer was used to update songs or recharge the battery. The battery could also be charged with a power adapter that was included with the first four generations. The third generation began including a dock connector, allowing for FireWire or USB connectivity. This provided better compatibility with PCs, as most of them did not have FireWire ports at the time. The dock connector also brought opportunities to exchange data, sound and power with an iPod, which ultimately created a large market of accessories, manufactured by third parties such as Belkin and Griffin. The second generation iPod Shuffle uses a single 3.5 mm jack which acts as both a headphone jack and a data port for the dock.

Eventually Apple began shipping iPods with USB cables instead of FireWire, although the latter was available separately. As of the first generation iPod Nano and the fifth generation iPod Classic, Apple discontinued using FireWire for data transfer and made a full transition to USB 2.0 in an attempt to reduce cost and form factor. With these changes, FireWire could only be used for recharging.

iPod dock connector

Introduced in the third-generation iPod, a 30-pin dock connector allows iPods to be connected to a variety of accessories, which can range from televisions to speaker systems. Some peripherals utilize their own interface, while others use an iPod's own screen for access. Such accessories may be used for music, video, and photo playback. Because the dock connector is a proprietary interface, the implementation of the interface requires paying royalties to Apple.

Accessories

Many accessories have been made for the iPod line. A large number are made by third party companies, although many, such as the late iPod Hi-Fi, are made by Apple. This market is sometimes described as the iPod ecosystem. [Darlin, Damon. [http://www.nytimes.com/2006/02/03/technology/03ipod.html?ex=1296622800&en=91f4e87dd848693f&ei=5088 The iPod Ecosystem] . "New York Times", 2006-02-03. Retrieved on 2006-08-14.] Some accessories add extra features that other music players have, such as sound recorders, FM radio tuners, wired remote controls, and audio/visual cables for TV connections. Other accessories offer unique features like the Nike+iPod pedometer and the iPod Camera Connector. Other notable accessories include external speakers, wireless remote controls, protective cases/films and wireless earphones. [ [http://www.etymotic.com/ephp/er88.aspx In-The-Ear Bluetooth Earphones] . Retrieved on 2007-02-17.] Among the first accessory manufacturers were Griffin Technology, Belkin, JBL, Bose, Monster Cable, and SendStation.

The white earphones (or "earbuds") that ship with all iPods have become symbolic of the brand. Advertisements feature them prominently, often contrasting the white earphones (and cords) with people shown as dark silhouettes. The original earphones came with the first generation iPod. They were revised to be smaller after Apple received complaints of the earbuds being too large. The revised earphones were shipped with second through early fifth generation iPods, the iPod Mini, and the first generation Nanos. The earbuds were revised again in 2006, featuring an even smaller and more streamlined design. This third design was shipped with late fifth generation iPods and the second-generation nanos. All first generation iPod Shuffles and the second generation up until 30 January 2007 (when color models were introduced) were shipped with the second design; those that shipped after that date were destributed with the third design of the earbuds.

In 2005, New York's Metropolitan Transportation Authority placed advertisements on the subways warning passengers that "Earphones are a giveaway. Protect your device", [Dianner.

Bass response

The third generation iPod had a weak bass response, as shown in audio tests.Machrone, Bill. [http://home.comcast.net./~machrone/playertest/playertest.htm iPod audio measurements] , "PC Magazine", 2005. Retrieved on 2007-02-17.] [Heijligers, Marc. [http://members.chello.nl/~m.heijligers/ipod/Performance/measurements.html iPod audio measurements] . Retrieved on 2007-02-17.] The combination of the undersized DC-blocking capacitors and the typical low-impedance of most consumer headphones form a high-pass filter, which attenuates the low-frequency bass output. Similar capacitors were used in the fourth generation iPods. [Heijligers, Marc. [http://homepage.mac.com/marc.heijligers/audio/ipod/engineering/engineering.html iPod circuit design engineering] , May 2006. Retrieved on 2007-02-17.] The problem is reduced when using high-impedance headphones and is completely masked when driving high-impedance (line level) loads, such as an external headphone amplifier. The first generation iPod Shuffle uses a dual-transistor output stage, rather than a single capacitor-coupled output, and does not exhibit reduced bass response for any load.

Models

The iPod line has been upgraded many times, and each significant revision is called a "generation". Only the most recent (highest numbered) generation and refurbished units of previous generations of the iPod line are available from Apple for each model (Classic, Nano, Shuffle, Touch). Each new generation usually has more features and refinements while typically being physically smaller and lighter than its predecessor, while usually (but not always) retaining the older model's price tag. Notable changes include the touch-sensitive click wheel replacing the mechanical scroll wheel, use of color displays, and flash memory replacing hard disks.

The software bundled with the first generation iPod was Macintosh-only, so Windows users had to use third-party software like ephPod or XPlay to manage their music. When Apple introduced the second generation of iPods in July 2002, they sold two versions, one that included iTunes for Macintosh users and another that included Musicmatch Jukebox for Windows users.

Current iPods no longer ship with iTunes, which must be downloaded from Apple's website.

In December 2002, Apple unveiled its first limited edition iPods, with either Madonna’s, Tony Hawk’s, or Beck’s signature or No Doubt's band logo engraved on the back for an extra US$50.

It had a black case with a red click wheel and the back had the engraved signatures of U2's band members. This iPod was updated alongside the iPod Photo and fifth generation iPod.

On 13 October 2006, Apple released a special edition 4 GB red iPod Nano as part of the Product Red campaign. An 8 GB version was released three weeks later and both of them sold for the same price as the standard models. US$10 from each sale is donated to The Global Fund to Fight AIDS, Tuberculosis & Malaria. On 5 September 2007, Apple also added a Product Red iPod Shuffle model. They did not disclose how much will be donated to charity from this model. Apple also released Special Edition Harry Potter iPods to accompany the iPod Photo. These were engraved with the Hogwarts Crest on the back and were only available to purchasers of the "Harry Potter" audiobooks. They were updated when the fifth generation iPods were released, but were only available for a limited time.

Since October 2004, the iPod line has dominated digital music player sales in the United States, with over 90% of the market for hard drive-based players and over 70% of the market for all types of players.

In addition to its reputation as a respected entertainment device, iPods have also become accepted as business devices.

Criticism

Battery issues

The advertised battery life on most models is different from the real-world achievable life. For example, the fifth generation 30 GB iPod is advertised as having up to 14 hours of music playback. An MP3.com report stated that this was virtually unachievable under real-life usage conditions, with a writer for MP3.com getting on average less than 8 hours from an iPod.

iPod batteries are not designed to be removed or replaced by the user, although some users have been able to open the case themselves, usually following instructions from third-party vendors of iPod replacement batteries. Compounding the problem, Apple initially would not replace worn-out batteries. The official policy was that the customer should buy a refurbished replacement iPod, at a cost almost equivalent to a brand new one. All lithium-ion batteries eventually lose capacity during their lifetime [ [http://www.mp3newswire.net/stories/6002/li_ion.html The Curse of Lithium Ion Batteries] , "MP3 Newswire", 2006-01-06. Retrieved on 2006-11-30.] (guidelines are available for prolonging life-span) and this situation led to a small market for third-party battery replacement kits.

Reliability and durability

iPods have been criticized for their short life-span and fragile hard drives. A 2005 survey conducted on the MacInTouch website found that the iPod line had an average failure rate of 13.7% (although they note that comments from respondants indicate that "the true iPod failure rate may be lower than it appears"). It concluded that some models were more durable than others. [ [http://www.macintouch.com/reliability/ipodfailures.html iPod Reliability Survey] , "MacInTouch", 2005-11-28. Retrieved on 2006-10-29.] In particular, failure rates for iPods employing hard drives was usually above 20% while those with flash memory had a failure rate below 10%, indicating poor hard drive durability. In late 2005, many users complained that the surface of the first generation iPod Nano can become scratched easily, rendering the screen unusable.

Allegations of worker exploitation

On 11 June 2006, the British newspaper "Mail on Sunday" reported that iPods are mainly manufactured by workers who earn no more than US$50 per month and work 15-hour shifts.

Retrieved on 2007-03-20.] Apple investigated the case with independent auditors and found that, while some of the plant's labour practices met Apple's Code of Conduct, others did not: Employees worked over 60 hours a week for 35% of the time, and worked more than six consecutive days for 25% of the time.

Apple hired a workplace standards auditing company, Verité, and joined the Electronic Industry Code of Conduct Implementation Group to oversee the measures. On 31 December 2006, workers at the Longhua, Shenzhen factory (owned by Foxconn) formed a union. The union is affiliated with the world's largest and most powerful federation of trade unions, the All-China Federation of Trade Unions. [Bodeen, Chistopher.
