The AFL has announced a new $2.5 billion television rights deal - the biggest in Australian sports' history - that will see more games broadcast live in more parts of Australia than ever before.

Commencing in 2017 and running until 2022, the deal allows Foxtel to broadcast every match live, while giving Channel Seven three matches live per round in every state and territory, as well as coverage of the grand final and Brownlow Medal count.

The deal will keep the AFL season at 22 matches per-team, with the weekly schedule to remain largely the same as is currently in place, with one match on Friday night, two on Saturday afternoon, one on Saturday twilight, two on Sunday afternoon and one on Sunday twilight.

Significantly, all free-to-air matches will be broadcast in high definition by the Seven Network.

AFL chief executive Gillon McLachlan said he was proud to announce the deal, one that he says will continue to establish the code at the forefront of Australia's sporting landscape.

"The AFL's challenge is to stay Australia's game," McLachlan said.

"For our supporters, we want maximum reach and exposure. This deal delivers for our four pillars - players, clubs, supporters and the community."

Managing director of News Limited Rupert Murdoch said the deal represented a "substantial investment" from his side, and pledged dedication to improving the "national game".

"We have always believed this is the premium code in Australia, this is the national game," Murdoch said.

"We believe in the strength in the game, and we will do everything we can to make it stronger."

Last week, the NRL announced its own TV deal with the Nine Network worth around $925 million, with four matches per round to be broadcast on free-to-air television.

The NRL expects the deal to be worth just short of the AFL's $2 billion figure once pay TV agreements are reached.
