The National Football League is considering creating an ad network that spans all 32 team websites, reports Sports Business Journal.

The new ad network is a move in the league's plans to exert more control of the collection of sites than it has now. The idea has been floated to team owners before, most recently back in May, but was deferred until it could be studied a bit more.

A unified NFL ad network would grant access to national ad spending, where there is serious money to be made. Right now local team sites and the main NFL.com site lack significant reach to make a splash in that arena - but combined, they could offer millions of monthly visitors.

Video produced and provided by the NFL would contain ads sold by the league, regardless of which team site the video is used upon. Individual teams will also be able to sell ads within video they themselves created.
