YouTube One Channel
Earlier this year YouTube began the roll out of its new channel design called One Channel. After an optional adoption period and beta testing, on the 5th of June YouTube switched to a mandatory use of One Channel for all users. The aim in YouTube's own words is to "evolve from a video-based site to a channels-based site, where subscriptions rule."
One Channel is a good way to get users to become subscribers, which has become more critical than a few years ago. Mainly because people who subscribe to channels on YouTube generally watch more content more often than those who don't. They are also more likely to be the opinion leaders who informally influence people who surround them to watch the videos too. The new social buttons will also help to start conversations outside of the channel, allowing brands to build an ongoing relationship with its subscribers.
One of the main changes is the new dynamic layout making channels look good on any browser used, across all screens and devices and it allows you to customize how to organize your videos and playlist so it fits your audience in the best way.
