Music subscription service Rdio has expanded to video, today launching a movie and television streaming service called Vdio. Vdio functions like iTunes rather than like Netflix, allowing users to purchase and rent video content. Though it does not offer a subscription service, Vdio does incorporate social content discovery, allowing users to see what their friends are viewing. Vdio users are also able to create and share playlists. Pricing is similar to iTunes and Amazon, with a movie rental costing approximately $5 and TV shows priced at $3. Content must be purchased from the website, but can be viewed on an accompanying iPad app, which supports AirPlay. Rdio subscribers with premium Unlimited accounts will be offered a free $25 gift cer
