Beginning Wednesday, NFL teams can be fined for violating a newly introduced part of the league's social media policy.

According to two league memos obtained by ESPN, teams no longer can shoot video inside the stadium during the game and post it on social media, nor can they use Facebook Live, Periscope or any other app to stream anything live within the stadium.

Teams also can't take highlights of what happens on the field and make it their own by using their own video or posting highlights from television directly to social media. Teams also can't turn highlights into animated GIFs.

In conversation with the teams, sources said that league executives want to make sure that content generated within the stadiums, including game highlights, is hosted by team websites so that the league maintains control of what is disseminated.

Violations of the policy will cost teams up to $25,000 upon the first instance, up to $50,000 the second time and up to $100,000 for each additional violation of the policy.
