The CW Television Network (The CW) is a television network in the United States launched at the beginning of the 2006–2007 television season. It is a joint venture between CBS Corporation, the former owner 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.). According to its former President of Entertainment Dawn Ostroff, the network tries to "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).
