YouTube, the world’s largest video-sharing service, is looking beyond video to keep its homegrown stars — and their fans — from departing to competing platforms, reports VentureBeat.  The report also stated that amid competition from Facebook, Snapchat, and Twitter, “YouTube is developing a feature internally called Backstage where users can share photos, polls, links, text posts, and videos with their subscribers. Backstage is expected to launch by the end of the year, possibly this fall, on mobile and desktop, initially with select popular YouTube accounts and with limited features, VentureBeat has learned.”
