Big Ten still leads leagues in college sports revenue

The Big Ten Conference maintained its status as the nation's highest-revenue college sports league in fiscal 2013, new federal tax records show.

The 12-school Big Ten reported $318.4 million in total revenue for a fiscal year that ended June 30, 2013. That is just ahead of the $314.5 million reported by the 14-team SEC for a fiscal year that ended Aug. 31, 2013.

The Big Ten Network generated an after-tax profit of $13.4 million for the conference in fiscal 2013, up about $2.4 million from fiscal 2012.
