The CW [SEP] 2006–2011: Launch and early struggles
Like both UPN and The WB, The CW targets its programming towards younger audiences. CBS and Time Warner hoped that combining their networks' schedules and affiliate lineups would strengthen The CW into a fifth "major" broadcast network. One week before the network's official launch, on September 11, 2006, a new, full version of the network website was launched; the website began to feature more in-depth information about The CW's shows. The CW launched with a premiere special / launch party from the CBS Paramount-produced "Entertainment Tonight" at Warner Bros. Studios in Burbank, California on September 18, 2006, after a repeat of the tenth-season finale of "7th Heaven"; the same schedule was repeated on September 19, with the sixth-season finale of "Gilmore Girls" airing in the second hour of prime time.
