What name did YouTube Premium originally launch under in 2014? It originally launched as Music Key.

YouTube introduced Music Key in November 2014 as a subscription focused on music. It offered ad-free music videos from participating labels on YouTube, plus background and offline playback on mobile devices. The package also included access to Google Play Music All Access, Google’s existing paid music-streaming service.

Music Key was narrower than today’s YouTube Premium. Its main purpose was to make music viewing and listening more convenient, rather than remove advertising from every YouTube video. During its invite-only beta, users and executives found the music-only boundaries confusing—for example, some music-related videos did not qualify.

That feedback led YouTube to broaden and relaunch the service as YouTube Red in 2015. YouTube Red covered all YouTube videos, not just music, and added original programming. In 2018, YouTube Red was renamed YouTube Premium, while YouTube Music returned as a distinct music-focused service. Music Key, YouTube Red, and YouTube Premium are therefore successive names in the same subscription’s history.
