An estimated 1.4 million people lost power following the quake, mainly due to damaged electrical substations. Many San Francisco radio and television stations were temporarily knocked off the air. KGO-TV, the local ABC station in San Francisco, was off the air for about 15 minutes, while KRON-TV (at the time the region's NBC affiliate) was off the air for about half an hour, and KGO-AM (ABC News Radio) was off the air for about 40 minutes. About an hour and 40 minutes after the quake, Fox affiliate KTVU resumed broadcasting, with their news anchors, Dennis Richmond and Elaine Corral reporting from the station's parking lot. KCBS-AM (CBS News Radio) switched immediately to backup power and managed to stay on air despite a subsequent generator failure. KCBS later won a Peabody Award for their news coverage, as did KGO-TV. (All four network-affiliated TV stations (KRON, KGO, KTVU and CBS affiliate KPIX) would recover enough to broadcast continuous breaking news coverage of the aftermath of the quake for the next several hours, some of it picked up and broadcast nationally over their respective networks, as well as on CNN, in a manner anticipating later major catastrophes such as the 1994 Los Angeles earthquake and the 9/11 terror attacks.)
