After the revised proposal was rejected on July 28, Warner Communications and American Express restructured the purchase to include only Viacom as a partner, bowing Gulf+Western and MCA out from the partnership. The changes – which Justice Department officials acknowledged would "prevent any anti-competitive effect from arising" following the merger, by allowing other premium services to enter the market should the venture significantly raise licensing fee prices for films – led the Justice Department to drop its challenge to the merger agreement on August 12; the Department formally approved the deal the following day on August 13. When the deal was completed on September 6, 1983, the operations of The Movie Channel and Showtime were folded into a new holding company, Showtime/The Movie Channel, Inc., which was majority owned by Viacom (controlling 50% of the venture's common stock as well as investing $40 million in cash), with Warner Communications (which owned 31%) and Warner-Amex (which owned the remaining 19% interest) as minority partners.
