SANTA MONICA - After trumpeting ambitious plans to introduce elaborately produced sitcoms, talk shows and other TV-style programs to Yahoo, the head of the company's Media Group, Lloyd Braun, admitted Wednesday he was downsizing those efforts. Instead, the group will shift its emphasis to content acquired from other media companies or submitted by users.
    Braun, the former chairman of ABC Entertainment, has been the subject of speculation in recent weeks that he was set to quit after differences with Yahoo chief executive Terry S Semel.
    Braun has called a meeting of his group today (Friday) at which he will outline the new strategy which, he claims, will be endorsed in person by Semel.
    "I thought it would be a good time, given all the rumor and innuendo, for me to reiterate once and for all that I am not going anywhere," Braun said.
