While some people paid $100 dollars a pop to watch the big fight this weekend, others got the blow by blow of the Mayweather-Pacquiao bout on Periscope.
The app, owned by Twitter, allows people to live stream events using their phones. And apparently so many people did, it prompted Twitter's Chief Executive to tweet "And the winner is... Periscope."
"I mean your first instinct is like, 'Ok, this is kind of awesome.' But the next is, 'Ok, this is kind of piracy,'" said tech user Ginger Goforth.
Another tweet, this one from one of Periscope's co-founders, stated in part, "Piracy does not excite us."
A company spokesperson confirmed they received 66 reports from rights holders asking them to take down illegal feeds. They managed to take action against 30. The rest were already gone.
The company said broadcasting copyrighted content is against their policy and not at all what they want.
Still taking action, according to tech analyst Larry Magid, is a challenge.
"It's a game of whack a mole and companies that are responsible are going to try to obey the law and try to prevent users from uploading illegal material. And they can do that to a degree," says Magid. "YouTube has actually gotten pretty good at it. But it's difficult. It takes a while to get the technology in place and it's never going to be 100 percent."
Periscope and its competition, Meerkat, are a sign of the times, says Magid. And he calls this weekend's live streaming of the fight a watershed moment.
"I guess the question is, are live televised pay per view events going to go the way of recorded music? Is this the Napster for pay per view?"
However, he says the music industry has changed to cope with piracy and that other kinds of broadcasting can too.
He points to the number of phones being held up at any sporting event or rock concert and says they'll have to.
"They cannot ban cell phones at the park or at the fight arena, or in front of people's television sets. They have to figure out how they're going to co-exist with this. And to try to simply suppress it is going to be counter productive," explained Magid.
And some tech users agree.
"Unfortunately there's nothing you can do. So if you can't beat them, you have to join them, right?" said Michael Jeron.
A Periscope spokesperson says they respect intellectual property rights and are working to ensure there are "robust tools" in place to protect them. The app is just a month old.
