The fine folks at the YouTube Creator Blog this morning dropped an early heads up that starting sometime in November, we'll be able to watch YouTube videos offline "for a short period." It doesn't sound like this is full offline downloading, but instead you'll get temporary access while you're disconnected.
This upcoming feature will allow people to add videos to their device to watch for a short period when an Internet connection is unavailable. So your fans’ ability to enjoy your videos no longer has to be interrupted by something as commonplace as a morning commute.
Looking forward to it. In the meantime, be sure to subscribe to our YouTube channel, wont'cha?
