The WB Television Network (commonly shortened to The WB) is a former television network and present-day internet television network in the United States, that in its original television incarnation was launched on January 11, 1995 as a joint venture between Warner Bros. and Tribune Broadcasting. On January 24, 2006, CBS Corporation and Warner Bros. Entertainment announced plans to shut down the network and launch The CW Television Network later that same year. The WB Television Network shut down on September 17, 2006, and merged with UPN (which had shut down two days earlier) to form The CW.

As a television network, it aired programs targeting mostly teenagers and young adults, with the exception of its Saturday morning line-up of shows called Kids’ WB, which was geared towards children. It was re-launched as an online network on April 28, 2008 by Warner Bros. The new website allows users to watch shows of the former TV network, as well as shows formerly hosted on the now-defunct In2TV service. The website can only be accessed within the United States.
