Periscope is an app that was developed by Twitter and allows live broadcasting through your phone. I watch alot of concerts from people in the crowd, it is pretty cool. I watched UFC 201 through this as well because a guy was broadcasting it from front row, it is pretty damn cool that have a view from that pov. There are also people who broadcast it through their phones from their living room. Sounds shitty but if your not willing to buy the ppv, or go to the bar and want to watch it live then it is a good option. I like it better than finding a stream online because those are always laggy as fuck for me. Also awesome for a lot of other things, check it out if you're a poor POS who doesnt want to buy UFC like me.
Or, Kodi. Used to use Periscope as a last resort, but ever since I found Kodi streaming and watching UFC has never been easier.
It's a multimedia device that allows you to download addons that stream certain movies, TV shows, sporting events, etc..
