Television Production Partners, a consortium of 10 big U.S. companies--AT&T, Campbell Soup, Clorox, Coca-Cola, Coors, General Motors, MasterCard, McDonald's, Reebok and Sears--that had joined together to produce TV programming, has disbanded. TPP pulled the plug on three specials it was supplying to ABC:"Gail Sheehy's New Passages," which aired last week, but with no TPP advertiser participation; "Celebration for Humanity," that will not air; and one in conjunction with Ebony, that will likely air but without TTP's ad support. Jack Myers, TPP chairman-CEO, is still trying to line up some advertiser support, on an ad hoc basis, for TV movies TPP was to produce with Paramount TV and for Fox Broadcasting, according to an executive with knowledge of those deals. Mr. Myers did not return phone calls. The demise of TPP was first reported today in USA Today.
