Panther,you are correct in posting that the Big Ten schools are making a lot more money for their national tv rights(estimated in excess of $14 million per school for 2008-2009) than the other BCS conferences,especially the(estimated at about $3-3.5 million per school for 2008-2009) BE.The Big Ten tv amounts should increase in coming years.Also, the SEC tv money is estimated to about triple in their next contract(beginning next year) from the current estimated per school amount of $5.5 million.The three other(Pac-10,Big-12,ACC) BCS conference are in this general range also.
The easiest way for conferences to increase revenue is to expand to obtain new tv markets and have a FB championship game.This is what the ACC did in 2003-2004.
In addition,The Big Ten came up with the BTN to maximize their current tv markets.The SEC played the "SEC network" card and got ESPN to pony up extra money for their new tv deal.
Conferences like the ACC and Big 12 have already cashed in their FB championship game chips.Now they are looking to maximize their current markets with a possible conference/school network in their next tv deals.
The BE has not expanded to 12 to cash in on a FB championship game or to claim more tv market share.They do not seem to have any plan to try and catch up with the other BCS conferences financially.
The SEC and Pac 10 structures seem set at this time for different reasons.
However,the Big 10 still has not been able to expand to 12 to have FB championship game revenue and obtain an additional tv market.Look for that to change in the future.
Here is an unconfirmed Big 10 expansion rumor on the UConn Scout MB that involves Pitt.
