Live streaming gains ground as YouTube and Yahoo are adding the feature | Mobile Video Challenges Worldwide |

Anyone thinking the Wild West mentality of the online video space is fading hasn't looked very closely at the emerging live streaming video segment. Despite the technology being available for more than two decades, with Real Networks among the first to test it in a consumer-focused format, live streaming didn't catch the industry's attention until mid-2014 when then-Justin.TV owned game-streaming website Twitch emerged as the fastest-growing video site in the U.S.

What drove the rise of live streaming was a confluence of open-source innovation, user demand, and the vast improvements in broadband network capacity and online video streaming technology. Put more simply, the capability to stream live video smoothly wasn't quite there -- and users weren't sure what to use it for. All that changed over the past couple of years.
