O&Os and two affiliates that produce their own local news programming, which were all carry-overs from previous affiliations: O&Os WPIX in New York City and KTLA in Los Angeles started their news departments as independent stations and/or during early affiliations with other networks including DuMont; WCCB in Charlotte, North Carolina started its news operation as a Fox affiliate; and WISH-TV in Indianapolis has been airing local news since 1956. KTLA has the largest number of weekly hours devoted to local news programming of any CW affiliate with 89¾ hours of scheduled news each week. Eight other CW-affiliated stations maintained in-house news operations, but have since disaffiliated from the network or discontinued in-house production: WGN-TV in Chicago has maintained a news department since it launched as a CBS affiliate in 1948; the station – which, along with sister stations KTLA and WPIX, transitioned into a news-intensive outlet during its tenures with The WB and The CW – retains a news-heavy format after disaffiliating from the network in September 2016; Under Tribune Broadcasting ownership, WLVI in Boston produced an in-house 10:00 p.m. newscast, which was replaced in December 2006 with one produced by then-NBC affiliate (now independent) WHDH, after Tribune sold WLVI to that station's longtime owner Sunbeam Television; XETV-TDT in Tijuana, Baja California, Mexico (serving the San Diego market) retained the news department it launched in 1999 as a Fox affiliate when it joined The CW in August 2008; XETV's news department shut down on March 31, 2017, following the earlier announcement that the CW affiliation in San Diego would move to a subchannel of CBS affiliate KFMB-TV. In April 2012, KCWI-TV in Des Moines, Iowa broadcast a morning news and talk program, which transitioned from an in-house production to a brand extension during Good Morning America of ABC affiliate WOI-DT's morning newscast on April 11, 2016, as a result of Nexstar Broadcasting's acquisition of KCWI. For several years, WDCW in Washington, D.C. used reporters from Tribune's local bureau and anchors based from the studios of CBS-affiliated station WTVR in Richmond, Virginia, while then Tribune-owned KDAF in Dallas, KIAH in Houston and WSFL-TV in Miami used non-traditional formats (in the form of a newsreel-style program known as NewsFix, along with the morning show Morning Dose; both KDAF and KIAH had previously produced more traditional newscasts, launched during their WB affiliations, earlier in their tenures with The CW).
