Perlmutter movin' on up: Marvel Enterprises announced today that Isaac Perlmutter, Marvel's vice-chairman and largest shareholder, has been named CEO, effective Jan. 1. He'll replace President and CEO Allen Lipson, who is retiring after five years with the company.

It's pointed out, via The Beat, that Marvel changed its press-release boilerplate to boast "a library of over 5,000 characters"; just yesterday, it was touting some 300 fewer.
