Time Inc. CEO Jack Griffin was dismissed by Time Warner boss Jeff Bewkes after just five months on the job.

Why?

According to an internal memo sent last night, Griffin “did not mesh” with Time Inc.

There’s no immediate successor, but “an experienced interim management committee” will handle Time Inc in the meantime, composed of Howard Averill, Maurice Edelson and John Huey.

However…..In August 2010, not so long ago, Bewkes called Griffin “an exceptional executive who knows how to expand the reach and relevance of strong publishing brands, and he will be a champion of our high-quality journalism. As CEO, Jack will further advance our lead position in the industry and accelerate the expansion and innovation of our titles on all platforms.”

What a difference half a year makes.
