YouTube for Android and iOS gets suggested next video overlay
Google wants to make YouTube's mobile apps more sticky and get users to string more views back to back. And, in order to do that, Google has added acouple of new overlay options for content creators to use in the Android and iOS YouTube apps. Creators can now add overlays to videos suggesting another video to watch next, and more.
The two new options are InVideo Programming and Call-to-Action Overlays. InVideo Programming will automatically add overlays to videos in order to get the viewer to watch the next video in a channel's list. The Call-to-Action Overlays will start out only available to advertisers, but eventually will be made available to all channel operators and allow them "to share more information about the content of your video, raise interest in your channel, or your own web site."
