station KHTT won San Jose State broadcast rights beginning in 1987. From 1981 to 1986, KCBS was the flagship station for the San Francisco 49ers. In 1990, KCBS became the primary station for the Bay Area's Emergency Broadcast System after KNBR, the former primary EBS station, failed to activate the Emergency Broadcast System due to major technical malfunctions caused by the engineering department at KNBR during and the aftermath of the 1989 Loma Prieta earthquake. The Federal Communications Commission called the situation "revoked" as the decision was made to move its primary EBS status to KCBS after the major fail on KNBR. Common ownership with KPIX (1995–2017) In late November 1995, the Westinghouse Electric Corporation bought CBS, bringing the Bay Area's oldest radio station under common ownership with its oldest television station, KPIX-TV Channel 5, which Westinghouse had purchased from Associated Broadcasters in 1954. In May 2006, KCBS and KPIX-TV moved their news bureau in San Jose to the Fairmont Tower at 50 West San Fernando Street. This was, coincidentally, the location of Charles Herrold's original broadcasts. CBS management was unaware of the San Fernando Street address' history when the move was planned. However, once informed that this was the birthplace of KCBS, they recognized this at the bureau's opening celebration. In mid-March 2005, KCBS, along with nearly all of the other all-news stations owned by Infinity Broadcasting (which renamed itself CBS Radio that fall), began streaming its audio over its website, reversing a long-standing Infinity Radio policy of not doing so. (New York City's WCBS began streaming its programming online the previous December). Local commercials which are heard on the radio signal are replaced on the internet stream for nationally and regionally sponsored ads, a few public service announcements, station promos, promos of CBS Television shows, and repeats of pre-recorded feature segments already on the broadcast schedule (including StarDate and Science Today, produced by the University of California). In March 2010, KCBS and the other CBS Radio stations blocked Internet listeners outside the United States from accessing its live stream. In 2007, KCBS added an HD Radio digital sub-channel, and began identifying as "KCBS and KCBS-HD". On October 27, 2008, the station began simulcasting its full schedule over co-owned KFRC-FM (106.9) and that station's HD1 digital sub-channel. (KFRC-FM's previous "classic hits" format was moved to sub-channel HD2.) The stations' microphone flag now displays "740" on two sides of the
