drama "Mad Men" won't be returning to television until early 2012 because of a dispute between the channel and the show's creator, Matthew Weiner.

reported, citing people familiar with the matter, after his contract expired at the end of the show's fourth season last October.

As a part of the pending agreement, the channel proposed to shorten each episode by two minutes, add more product placement in the show and drastically cut the cast budget.

Weiner refused to accept the terms of the new deal, claiming the changes would make

Mad Men

a "different show."
