The Warner Brothers Network is a television network in the United States, founded by the Warner Bros film studio and Tribune Broadcasting in the mid-1990s. The network is typically referred to by its nickname, The WB.

Much like its contemporary UPN, the WB was a reaction to the success of the Fox Network and first-run syndicated programming during the late 1980s and early 1990s. WB's first programs were sitcoms and other cheap-to-produce fare; in 1995, WB also added the "Kids' WB" programming block, which mixed Warners' biggest hit shows (Tiny Toon Adventures, Animaniacs and later Batman: The Animated Series, all of which originated either on Fox or in syndication) with new productions and original shows.

After the Turner-Time Warner merger in 1996, Kids' WB formed an alliance with Cartoon Network, and over time, they have shared programming more and more.

The WB's breakout hits during the late 1990s were Buffy the Vampire Slayer in prime time, and the American version of Pokémon in the Kids' WB blocks, which they acquired from syndication in 1998. Buffy eventually moved to UPN in 2001.
