The Pulitzer Prize-winning critic wrote on his blog Wednesday that the hiatus is necessary to allow the public television stations that carry the show to plan their programs for the beginning of 2012.
Ebert also wrote that he hasn't been able to line up additional funding for the show although it is distributed by American Public Television to all 50 top markets.
The show is hosted by Associated Press movie reviewer Christy Lemire and Mubi.com film critic Ignatiy Vishnevetsky.
Ebert wrote that he and his producer wife, Chaz, really believe in the show and its mission to "provide an intelligent place for the discussion of movies."
