The YouTube Creator blog reveals that offline video viewing will be launched in November, but doesn’t reveal any details.

We’re always exploring ways to bring more viewers to your content. As part of this effort, later this year we’ll launch a new feature on YouTube’s mobile apps that will help you reach fans — even when they’re not connected to the Internet. 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 … 

It’s not known what YouTube means by ‘a short period’ means, with the commuting reference suggesting it might be as short as an hour or two, but TechGeek reports that an email to creators said that it would be 48 hours. YouTube updated its iOS app last month to enable you to continue watching one video while looking for another one.

It was revealed back in July that Google traffic, the bulk of which is YouTube, accounts for a quarter of all North American Internet traffic – which is why your ISP may be throttling the feed without your knowledge.

Thanks, Daniel, for the update
