In the past, casting was only supported from YouTube.com, so this is definitely a step in the right direction. Several Chromecast users did start to report that recently, they managed to see the dongle’s play to TV button popping up on embedded videos on Google+, in addition to other sites. A YouTube spokesperson said this, “With more videos coming to YouTube every minute we’re always experimenting with ways to help people more easily find, watch and share the videos that matter most to them. As always, we’ll consider rolling changes out more broadly based on feedback on these experiments.” This is one move that makes plenty of sense for YouTube, as it could allow folks to view videos for longer periods of time, and in turn, YouTube will be able to show more ads, now how about that for a win-win situation?
