A fan's live FA Cup video on Periscope had 139,000 viewers

"The Premier League have said they will take action against any fans broadcasting football matches on streaming websites via smartphones.
It is a new problem that is creeping into the game with fans inside stadiums filming the action on their phones and broadcasting it live on websites like the Twitter-owned Periscope platform.
One Manchester City fan who went to Selhurst Park on Saturday to watch his side's FA Cup clash with Crystal Palace decided to film and broadcast the entire match and pulled in an incredible 139,300 viewers."
