The CW Television Network (The CW) is a television network in the United States launched at the beginning of the 2006–07 television season. It is a joint venture between CBS Corporation, the former owners of United Paramount Network (UPN), and Time Warner’s Warner Bros., former majority owner of The WB Television Network. The “CW” name is derived from the first letter of the names of these corporations (CBS and Warner Bros.). The network features a lineup of shows that, according to its former President of Entertainment Dawn Ostroff, “appeal to people 18 to 34-years-old”. The network currently airs programming six days a week: Monday through Friday afternoons and evenings (in prime time), and Saturday morning children’s programming (under their The CW4Kids block).
The network debuted programming after its two predecessors, UPN and The WB, ceased independent operations on September 15 and September 17, 2006 respectively. The CW’s first two nights of programming—Monday and Tuesday, September 18 and September 19, 2006—consisted of reruns and launch-related specials. The CW marked its formal launch date on Wednesday, September 20, 2006, with a two-hour season premiere of America’s Next Top Model.
The CW lineup has featured on a mixture of programming that originated on both UPN and The WB along with its own original programs, mostly targeted towards women and young adults.
