Twitter's live-streaming app Periscope celebrated its first birthday this weekend. The company also released figures showing that since the mobile app went live in March 2015 the network has hosted over 200 million live broadcasts. In addition, Periscope users daily watch over 110 years of live video on iOS and Android devices.

Periscope's figures are impressive, but its apps do not rack up 1 million hours of video per day. Meanwhile, Google's YouTube reported on March 28, Monday its users watch hundreds of millions of hours of YouTube videos per day that result from billions of views, according to Tech Crunch.

YouTube is reportedly developing a live-streaming app that would take on Periscope. The Twitter company won an early battle against Meerkat, but Facebook has launched a live-streaming feature to all iPhone and Android users in the United States.

Facebook has been using mobile notifications to push live streams. In addition, the world's largest social network also now has 1.5 billion monthly active users (MACs).

However, it seems that some Facebook users are not fans of the mobile notifications. The company has announced it will offer a new setting that allows users to disable the mobile alerts for live-streamed videos.    

Periscope is certainly growing. It reported last August that its users were daily viewing 40 years of video and its user base had increased to 100 million.

However, it is interesting that Periscope just reported years of video watched per day instead of hours watched every day, and did not provide an update about its user base.

In related news Meerkat is pivoting away from live-streaming video after its launch at last year's SXSW festival. The app has had problems competing with Periscope and Facebook.

Meerkat has plans to become a social network where its users are always live, according to Engadget. It could function like video conference apps such as Google Hangouts and Skype, focusing on chats with friends and family rather than the whole world.

Meerkat founder Ben Rubin shares that the company had problems getting users to keep streaming video from the company's mobile apps. The main difference is that Facebook and Twitter's Periscope have a larger social media base.
