Another great feature is "One Channel branding for video creator channels." YouTube recently updated the desktop interface, calling it "One Channel" and this update allows businesses to carry that branding through to the mobile experience.

Businesses need to take advantage of video and these updates to reach a larger audience. If you haven't yet started using video, what's holding you back?

Customers are also using apps and social networks like Foursquare and Yelp to find, rate and review local businesses.
