As multiple sources claim, YouTube is about to launch its two separate subscription services till the end of 2015: Music Key, and another unnamed service aimed at YouTube’s premium content creators. The biggest video streaming site in the world will be a mix of free (ad-supported) content and premium videos, that will be positioned behind a paywall. Though Youtube has till now been a free ad-supported service, the company has now decided to offer users new ways to make money. The biggest change for most YouTube users will be the music that inevitably finds its way behind the upcoming paywall. There may be several models of category-specific subscription services on the platform. Music Key may be coupled by subscriptions aimed at children’s programming or gamers at some time it the future.
