So cross board memberships of media and press companies is not preplanned? It just happened?
the people who operate in those circles are usually very small groups
for example, the people who sit on unsecured creditor committee boards for very large corporate bankruptcies pretty much know each other if not by name then by reputation
its a very narrow skill and as a result it cross pollinates a lot
board members will find attorneys they really like and vice versa and they work to get each other into positions to work together
its not conspiracy, its an effort to avoid having to work with obstinant and difficult people so they can get the job done
I suspect the same is true in other specific industries
