Why did Reliance invest $200 million in Glance InMobi?

Glance is an app that allows you to lock your screen. It's not like any other lock screen software, though. Instead of showing you monotonous themes and wallpapers, it will provide you with new stuff. A short movie, a news piece, or even a fast game (after it acquired short-video app Roposo). You can swipe through the story/video to locate something that strikes your interest, and when you click on it, an embedded browser opens to show you the entire story/video.
