The politics inside a studio are self-defeating at the studio level, but I suppose they help those individuals involved.
I think it's like that at most, if not all, studios. I'd point to Warner Brothers for a perfect example of that. Each department (much less each division) actively works against all other departments. The television and movie divisions are actively at war with each other, and simply don't work together ... ever.
jmsnews.com has an archive of J. Michael Straczynski's posts over the years. Search for Warner or WB. It's fascinating.
