Zap2it

Zap2it is an American website and affiliate network that provides local television listings for areas of the United States and Canada. The site is produced by Tribune Media Services (TMS), part of the publishing division of Chicago-based Tribune Media. Zap2it affiliates include Wave Broadband, Cox, Dish Network, Disney, The New York Times, the Los Angeles Times, and The Washington Post. 
TMS first began to offer online listings services as a content provider to the online services Prodigy in the late 1980s and America Online in the early 1990s. TMS launched its first branded online television listings service, TV Quest, in 1993 on the AppleLink online service. TV Quest later migrated to Apple’s eWorld services and to the internet in the mid-1990s.
n early 2007, Zap2it released enhanced television listings on its main site. Upgrades to the product included improved performance, better customization capabilities and the introduction of sharing tools and a user rating system. Following a testing period, the television-listings product was made available to affiliates.
In 2008, a revised movie-showtimes product was developed on the main site. It more prominently showcased movie trailers and offered expanded cast and crew lists which linked to celebrity profile pages.
