LOS ANGELES — YouTube is launching a subscription plan in the U.S. called Red that will combine ad-free videos across its service with on-demand unlimited streaming music for $10 a month. The plan is targeted at people who frequently click to skip ads and yet wouldn't mind giving financial support to their favourite video creators, who'll share in the new revenues. It comes as streaming services like Hulu, Pandora, Spotify and TuneIn offer ad-free as a paid option. The plan includes exclusive access to new videos launching next year, as well as the YouTube Music Key service for music videos. It also comes with features such as the ability to download videos to mobile devices and have music playing in the background while using other mobile apps.
