Channels with Verified Names
Verification badges 
are applied to a YouTube channel’s connected Google+ identity. This badges help visually confirm the authenticity of a brand. When you find the badge on a channel for a popular celebrity or business, you can be sure that the channel actually belongs to them. The verification checkmark only appears to the right of the channel name, and “Verified” appears in a popup if you point your cursor at it.
These badges are applied with discretion to applicable official businesses, brands, organizations, and public figures.
