Even while they are issuing pink slips and otherwise cutting costs at their news units, many TV stations around the country are expanding their news programming. Bloomberg News reported today (Thursday) that several stations are dropping expensive syndicated programming and replacing it with newscasts. For example, it noted, Fox-owned Detroit station WJBK-TV has replaced reruns of Seinfeld at 11 00 p.m. with a newscast. Tribune-owned KTLA in Los Angeles has launched a one-hour newscast at 1 00 p.m. and Young Broadcasting, which has filed for bankruptcy protection, has added an hour of news at 10 00 on KRON-TV in San Francisco. Jack Abernethy, CEO of Fox stations,told Bloomberg "Local news is less expensive and has better revenue potential than many syndicated programs."
