Los Angeles), covering 28% of the U.S. Overview On the day of the network launch announcement, The CW immediately announced it had reached ten-year affiliation agreements with Tribune Broadcasting and CBS Television Stations. Tribune originally committed 16 stations that were previously affiliated with The WB (including its flagship broadcast stations WGN-TV in Chicago, KTLA in Los Angeles and WPIX in New York City; another committed station, KSWB-TV in San Diego, joined Fox in August 2008, and two others, WLVI-TV in Boston and WCWN in Albany, New York were respectively sold by Tribune to Sunbeam Television and Freedom Communications shortly after the network launched), while CBS committed 11 of its UPN stations (including WKBD in Detroit, WPSG in Philadelphia, KBHK-TV (now KBCW) in San Francisco and WUPA in Atlanta). These stations combined to reach 48% of all television households in the United States. Both companies also owned several UPN and WB-affiliated stations that did not join The CW in overlapping markets (such as Seattle, Philadelphia and Dallas). As part of its affiliation agreement with the network, the Tribune Company agreed to divest its ownership interest in The WB (a move it made partly to avoid shouldering shutdown costs for The WB) and did not acquire an equity stake in The CW. The network stated that it would eventually reach 95% of all U.S. television households. In markets where separate affiliates of both UPN and The WB operated, only one station became a CW affiliate. Executives were on record as preferring the "strongest" stations among The WB and UPN's existing affiliates. As one example, the new network's first affiliate outside the core group of Tribune and CBS-owned stations, WJZY in Charlotte (which was later acquired by Fox Television Stations and converted into a Fox O&O in July 2013), was tied with Atlanta O&O WUPA as UPN's fifth highest-rated station. In most cases, it was obvious where the new network would affiliate; there were only a few markets (such as Philadelphia, Miami–Fort Lauderdale, Boston, Charlotte, and Atlanta) where the WB and UPN affiliates were both relatively strong in terms of local overall viewership. For example, one of the earliest affiliates to be announced outside the core group, WKCF in Orlando, Florida, had not only been The WB's highest-rated affiliate for the virtual entirety of that network's run, but had also been the fourth highest-rated television station in Central Florida.
