As Jeff Bewkes whittles away at the Time Warner empire, it’s become clear that the company will have unraveled the two great megamergers that created its current shape.

Time Warner said the nomination of Jonathan Miller, the former chairman and chief executive of its AOL Internet unit, violated a non-compete agreement entered with Mr. Miller.

Richard D. Parsons, left, Time Warner’s chairman, said he was likely to step down in the next year, clearing the path for the chief executive, Jeffrey L. Bewkes, to assume the role.

The move spotlighted the company’s future as a pure content provider and signaled a renewed focus on its Warner Brothers movie studios and Turner Networks.
