What do you get out of winning the fantasy season? Is it just the benefit of knowing you picked better then the other guy?

Titus said that someone of you play in multiple leagues - do you win anything from those?

More or less asking because i dont know the 1st thing about fantasy football. I know you pick your team and then watch them throughout the season. Cox or DirectTv is offering to follow your drafted players so there has to be something big outta it.
