streaming news channels starting with its sister stations in Chicago, Miami, Philadelphia and Boston launching on January 20; the said channel was launched on March 17, 2022. On September 12, 2022, KNBC premiered a new 30-minute 3 p.m. newscast, followed by NBC Nightly News. News team KNBC has had a very stable news team over the years: weeknight anchor Colleen Williams (who also occasionally reports for MSNBC and NBC News) and sports anchor Fred Roggin (also has the nickname "The Dean of L.A. Sports" and serves as a commentator for NBC's Olympics coverage) have each been at the station at least thirty years or more. Former chief weathercaster Fritz Coleman (who like Roggin, has also occasionally appeared on The Tonight Show, and once hosted a late-night variety show for KNBC called It's Fritz from 1989 to the early 1990s) worked at the station from 1982 until his June 2020 retirement. Former anchor Paul Moyer worked two stints at channel 4; first from 1972 to 1979 (when he began a 13-year run at rival KABC-TV) and from July 1992 until his April 2009 retirement. Like Moyer, anchor Chuck Henry was also a mainstay at KABC-TV, before making the move to channel 4 in January 1994. Kelly Lange, Stu Nahan, John Schubeck, Tritia Toyota, Jess Marlow, David Sheehan, John Beard and Nick Clooney are other notables who have worked on KNBC's newscasts in the past. Another KNBC alum of note is consumer reporter David Horowitz, whose long-running syndicated series, Fight Back!, began on channel 4 and was produced and distributed by NBC and Group W. In 1987 during an afternoon newscast, a gun-wielding mental patient gained access to NBC Studios and took Horowitz hostage live on-air. With the gun pressed to his side, Horowitz calmly read the gunman's statements on camera. The man, identified as Gary Stollman, was caught with a toy gun and was arrested by local police. It led Horowitz to start a successful campaign to ban "look-alike" toy guns in several states, including California and New York. Tom Brokaw began his NBC career as an anchor and reporter at KNBC in 1966, staying until he went over to national work for NBC News in 1973. Other notables who have worked at KNBC early in their careers prior to joining the network include Bryant Gumbel, Ross Porter, Pat Sajak, Kent Shocknek, Bob Abernethy, Keith Morrison and Tom Snyder.
