"KPIX, Baltimore's WJZ and Philly's KYW are former Westinghouse stations of course today still use Eyewtiness News, and in the case with WJZ and KYW, since the 60s. On the other hand former Westinghouse stations Boston's WBZ and Pittsburgh's KDKA have long since dropped the Eyewtiness News name."
Interesting background info - thanks. Since nobody bit on my trivia question - I'll answer it myself. In San Francisco, Westinghouse bought 95.7 FM in the early 90s, and turned it into KPIX radio, the "FM News Station." That was the same time that KPIX-TV tried its experiment with "early prime time," with CBS network shows running between 7 and 10. KTVU (Fox) had huge ratings with their 10 O'Clock News, and KPIX thought they could improve their ratings with late news at 10. To capitalize on the "synergy" (ha, ha) with the radio station, they dropped "Eyewitness News," and re-titled in "KPIX 5 News at 10." (or "...at 6"). It was amusing watching the reporters stumble over that clumsy handle at the end of their live reports. Both experiments (early prime and KPIX radio) were disasters. They didn't make a dent in KTVU's ratings, and KPIX radio was an amateurish farce. I remember being amazed that Westinghouse - one of the originators of All News radio (KFWB in LA, 1010 WINS in NY) couldn't figure out how to run a newsradio station. Early prime was dropped when Westinghouse bought CBS, and "Eyewitness News" was back.
