Retlaw Broadcasting is reportedly in the process of selling its CBS affil in the Salinas/Monterey market to Smith Broadcasting Group for an estimated $ 5 million-$ 6 million.The Disney family controls Retlaw, which owns six TV stations in small markets, including KJEO in Fresno. The latter station (and possibly all of the stations) are said to be on the market, but not part of the pending KMST deal. Retlaw purchased KMST several years ago for an estimated $ 10 million-$ 12 million, but the station has failed to perform well. Exex for Retlaw and Smith, which owns nine TV stations in medium- and small-sized markets, were unavailable for comment late yesterday. Retlaw prez Ben Tucker is a former head of the CBS affiliates group. Sources said KMST, which switched to an early 7-10 p.m. prime time earlier this year along with its larger cousin KPIX-TV in San Francisco, is contemplating a switch back to an 8-11 p.m. prime time.
