Life without ESPN or the national championship game

Well the National Collegiate Athletic Associate (NCAA) college football championship game between Louisiana State University (LSU) and the University of Alabama is well under way tonight. How did ESPN get the rights to so many bowl games and the national championship game this year? The television executives over at the American Broadcasting Company (ABC) should have trumped ESPN and taken over the rights to the game. Could the advertising rights to a national championship game on ESPN be worth more than the same rights on ABC?
