Vessel launched as a YouTube alternative with exclusive early access to ad-free content for $3 a month. Beginning today, it's available for Android in beta form. The service launched in March for iOS with videos from A&E, Rheet & Link, Unbox Therapy, Warner Music Group and others. While most of the content is available for free, subscribers get early access to select videos and an ad-free experience. To help it become a destination for impatient video fans, the company has been attempting to lure YouTube stars away from the Google-owned video site. Now it just needs to lure eyeballs away.
