In 1952, when Mr. Reagan was president of the actors' union and MCA was his talent agent, the company got a special waiver from SAG's rules that allowed it to engage in unlimited production of television shows.

MCA, then the largest talent agency in Hollywood, was the only one ever given such a blanket exemption.
