The most over-hyped fight in a decade watched an aging Mayweather hold onto his undefeated record against Pacquiao, whose career is also on the wane. Outside the ring, another battle was being fought: Pay-Per-View vs. Periscope, Twitter's live-streaming app. The fight cost viewers a hefty $100 Pay-Per-View fee, which could be manageable with a large party gathered around a big screen TV. But, the fee remains a huge obstacle for most viewers, especially those without enough friends to split the bill. Periscope viewers could even tune into a ringside live stream thanks to these guys. Although some low-maintenance users just aimed their smartphone at their Pay-Per-View feed to live-stream the fight.
