Ha!

Ha! The Comedy Network, owned by Viacom, was one of the first American all-comedy channels available to basic cable subscribers. Launched on April 1, 1990, it competed with The Comedy Channel from the HBO unit of Time Warner.

Ha!'s schedule vs. Comedy Channel's schedule

While The Comedy Channel (which was launched on November 15, 1989) broadcast mostly low-budget original programming, Ha!'s schedule featured sitcom and sketch comedy reruns (many of which had been previously licensed for sister network Nick at Nite) as well as complete 90-minute reruns of Saturday Night Live from the sixth through sixteenth seasons. The first "SNL" to air was hosted by Susan Saint James from October 1981.

Ha! and Comedy Channel merge to create Comedy Central

The two networks merged to create Comedy Central, which began airing on April 1, 1991.
