Among other efforts, Twitter’s video unit is reportedly testing a feature that encourages users to draw doodles directly on live streams.

The experimental feature has been named Sketching, sources tellThe Next Web, and includes various drawing tools from your standard line to an eyedropper with which users can change the color of onscreen objects.

Along with Facebook, the test is also clearly aimed to Snapchat, which already offers many of these same features.

Despite all the competition, Periscope is doing quite well. Since its launch in March of 2015, the app has been used for more that 200 million broadcasts. Plus, Periscope users now watch around 1 million hours -- or close to 110 years -- of live streams every single day. And that stat only includes live streams viewed via Periscope’s iOS and Android apps.

Among other factors, the service received a boost when Twitter decided to start embedding live-video broadcasts directly into tweets at the beginning of the year.

For Twitter, the only problem is that its rivals have no intention of letting Periscope own the live-streaming space.

On the contrary, Google is readying a live-streaming app that will be closely integrated with YouTube, while Facebook can’t seem to scale its live-video feature fast enough.  

In fact, Facebook is preparing to prominently place a video tab right in its popular Messenger app.

Facebook also plans to roll out a number of new video-based features, including Video for Groups and Events, with which users can more easily share live video with particular friends and family.

The social giant recently tweaked its algorithm so that Facebook Live videos would appear more prominently in users’ News Feeds.
