the war in Europe. The vivid coverage was a prelude to television's rapid growth after the war ended. In the spring of 1946, the station changed its frequency from VHF channel 1 to channel 4 after channel 1 was removed from use for television broadcasting. From 1946 to 2009, it occupied the 66–72 MHz band of frequencies which had been designated as "channel 3" in the pre-1946 FCC allocation table. It was renumbered Channel 4 in the post-war system (DuMont-owned WABD, now WNYW—had been designated as "Channel 4", before that station moved to the current channel 5 but was only required to retune its video and audio carriers downward by 2 MHz under the new system). In October 1948, WNBT's operations were integrated with those of sister stations WNBC radio (660 AM) and WNBC-FM (97.1). The station changed its call letters on October 18, 1954, to WRCA-TV (for NBC's then-parent company, Radio Corporation of America or RCA) and on May 22, 1960, channel 4 became WNBC-TV. NBC had previously used the callsign on its television station in New Britain, Connecticut, from 1957 until it was sold earlier in 1960 (that station is now WVIT, and is once again an NBC-owned station). WNBC-TV also earned a place in broadcasting history as the birthplace of The Tonight Show. It began on the station in 1953 as a local late night program, The Steve Allen Show, and NBC executive Sylvester "Pat" Weaver brought it to the network in 1954. Studio 6B, the show's home under Jack Paar, Johnny Carson and today Jimmy Fallon, was the news studio for WNBC while Tonight was produced in Los Angeles. On June 1, 1992, channel 4 dropped the -TV suffix from its call letters (following the sale in 1988 of its sister radio station WNBC, which is now WFAN) and became simply WNBC, with the new branding slogan along with a new station logo and name "4 New York". The accompanying station image campaign was titled "We're 4 New York" and featured a musical theme composed by Edd Kalehoff. WNBC was rebranded again as "NBC 4" on September 5, 1995, with its newscasts being renamed NewsChannel 4. In July 2007, the "4 New York" branding was revived part time, but in March 2008, it was revived full time. During the terrorist attacks of September 11, 2001, the transmitter facilities of WNBC, as well as eight other New
