Cap Cities, the ABC network's parent company, and the Hollywood trio said each side would invest $100 million in the venture and will produce programming for all dayparts. When the three entertainment moguls joined forces last October no precise plans were revealed. Now, the seven-year deal will provide the new company with an outlet for at least some of their efforts.
