Context:
In 1990, Thomas S. Murphy delegated his position as president to Daniel B. Burke while remaining ABC's chairman and CEO. Capital Cities/ABC reported revenues of $465 million. Now at a strong second place, the network entered the 1990s with additional family-friendly hits including America's Funniest Home Videos (which has gone on to become the longest-running prime time entertainment program in the network's history), Step by Step, Hangin' with Mr. Cooper, Boy Meets World and Perfect Strangers spinoff Family Matters, as well as series such as Doogie Howser, M.D., Life Goes On, cult favorite Twin Peaks and The Commish. In September 1991, the network premiered Home Improvement, a sitcom starring stand-up comic Tim Allen centering on the family and work life of an accident-prone host of a cable-access home improvement show. Lasting nine seasons, its success led ABC to greenlight additional sitcom projects helmed by comedians during the 1990s including The Drew Carey Show; Brett Butler vehicle Grace Under Fire; and Ellen, which became notable for a 1997 episode which served as the coming out of series star Ellen DeGeneres (as well as her character in the series) as a lesbian.
