At the end of last October YouTube announced and unveiled the first instances of a new interesting beast: the YouTube Merch Store.
Here is the Google-YouTube official announcement:
"We’re launching a feature called the Merch Store that will allow YouTube partners to offer fans merchandise directly on your channel.
Fans will be able to buy artists’ merchandise, digital downloads, concert tickets and even unique experiences like meetups.
These features are made possible through affiliates like Topspin for merchandise, concert tickets and experiences; Songkick for concerts; and iTunes and Amazon for music downloads."
