West Coast operations (including KNBC, KVEA and NBC News' Los Angeles bureau) into one area. The studio opened on February 1, 2014. Shortly thereafter, NBCUniversal named the new broadcast center in honor of former KNBC and NBC News anchor/reporter Tom Brokaw, christened the Brokaw News Center. In fall 2007 with the rollout of digital broadcasting, the station began airing a 24/7 newschannel News Raw on the .2 subchannel. KNBC shut down its analog signal, over VHF channel 4, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition UHF channel 36, using PSIP to display KNBC's virtual channel as 4 on digital television receivers. Since the station qualified for the nightlight clause in the DTV Delay Act, it was required to keep its analog signal on for two weeks from June 12 to 26, 2009 to inform viewers of the digital television transition, consisting of a loop of digital transition public service announcements, while the digital channel was used for normal programming. On January 1, 2014, Universal Sports transitioned into a cable- and satellite-exclusive service, causing its affiliates (such as KNBC) to replace the network and remove the channel from their digital signals entirely. NBC California Nonstop KNBC operated NBC California Nonstop, a collaboration between KNBC and two other NBC-owned stations in California (KNSD in San Diego and KNTV in San Jose) which launched on May 3, 2011, and replaced programming from NBC Plus on the second digital subchannels of all three stations. In the case of KNBC, it was the second news-oriented digital channel operated by the station, as digital channel 4.2 featured a rolling news format under the name NewsRaw (which moved from digital channel 4.4 upon Weather Plus' December 1, 2008 shutdown), before the launch of California Nonstop. Each station produced a local newscast at 7 p.m. that was tailored to their respective market. For the Los Angeles feed of the channel, Colleen Williams anchored the hour-long Nonstop News LA. NBC California Nonstop ended on December 20, 2012, when Cozi TV was launched. Programming KNBC is the flagship station for The Kelly Clarkson Show and Access Hollywood (and its afternoon counterpart) which is produced by KNBC, both of which also air on other NBC owned-and-operated stations.
