ABC OLYMPIC COVERAGE IS CALLED TOO PARTIAL
The president of the International Olympic Committee has protested what he calls the overemphasis on American athletes in ABC's television coverage of the Games. Peter Ueberroth, the president of the Los Angeles Olympic Organizing committee, characterized the protest as a ''stern message'' that ABC, with its flag-waving emphasis on American athletes, threatened to diminish the ''international flavor'' of the Games in the eyes of the American public. The president of the international committee, Juan Antonio Samaranch, made the protest in a letter to the Los Angeles committee. 'A Consensus' of Board Mr. Ueberroth, who disclosed receipt of the letter at an informal news briefing Thursday night that had been called to discuss traffic problems, said that it repesented ''quite a consensus'' of the nine-member I.O.C. executive board and that he had urged the network ''to consider trying to give a good focus'' to its coverage.
