Marc Glaser has an excellent interview with MSNBC.com general manager Charlie Tillinghast on OJR. One of the most interesting bits comes before the Q&A:

A "source with inside knowledge" tells Glaser "the TV joint venture is likely to end in the next three to six months, but the complicated 99-year deal between Microsoft and NBC is quite expensive to break up."

Here's what the source said: "Both [TV channel] partners are motivated to change the relationship and will do so soon. The deal is pretty much impossible to get out of or modify without the consent of both parties. If that weren't the case, it would have cratered long ago." (Via Lost Remote)
