Veteran newsman Stan Chambers, who was hired by KTLA almost a year after its 1947 launch and remained with the station until his retirement in 2010, was given the honor of "throwing" a ceremonial mock switch from the analog to digital position, signaling the engineers to shut down the analog signal at its Mount Wilson transmitter site at 10:45 p.m., during KTLA's "Prime News" telecast. Covering the on-air event for KTLA was Stan's grandson, reporter Jaime Chambers. As part of the SAFER Act, KTLA temporarily restored its analog signal 15 minutes later at 11:00 p.m. to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
