The CW Television Network (The CW) is a television network in the Unite States launched at the beginning of the 2006-2007 television season. It is a joint venture between The CBS Corporation, owners of UPN, and Warner Brothers, majority owner of The WB. The name was derived from the first letter of the names of two of these corporations (CBS and Warner Brothers). It features a mixture of programming from both UPN and The WB television networks, which ceased independent operations on September 15 and September 17, 2006 respectively. According to The CW's President of Entertainment Dawn Ostroff, the network's "shows are going to appeal to women 18 to 34-year-olds."
