rights, but which were unavailable from the Criterion Collection; however, Criterion published the Classic Collection films. In 2005, Image Entertainment bought HVE making it the exclusive distributor of Criterion Collection products until 2013. Online ventures and marketing The Criterion Collection began to provide video-on-demand (VOD) in partnership with Mubi (formerly The Auteurs) in 2008. In February 2011, Criterion began switching its VOD offerings exclusively to Hulu Plus. In November 2016, FilmStruck, a film streaming service from Turner Classic Movies, succeeded Hulu as the exclusive streaming service for the Criterion Collection. Some Criterion films were streamed by Kanopy. On October 26, 2018, Warner Bros. Digital Networks and Turner announced that FilmStruck would shut down on November 29. Criterion stated in a blog post that it was "trying to find ways we can bring our library and original content back to the digital space as soon as possible". On November 16, 2018, Criterion announced the launch of the Criterion Channel as a standalone service, wholly owned and operated by the Criterion Collection, in the United States and Canada. Some of the VOD service's offerings are also available through HBO Max, WarnerMedia's streaming platform . Criterion also maintains a YouTube channel to market its films. One notable feature is the "Three Reasons" playlist, in which the company provides three reasons that a film is worth watching or has entered the Criterion catalogue.
