For instance, https://vimeo.com/ott is an effective (albeit expensive) option, powering Dropout (formerly CollegeHumor) and other brands and allowing them to focus on content. Dropout, in particular, has found an effective model of releasing short clips from their improv-heavy shows on social video platforms, gaining virality there while subtly reminding new and old fans that they can find full episodes, and support on-screen and off-screen talent, by subscribing to the brand directly. Their growth would be impacted by the loss of a marketing channel, but not their underlying subscription fundamentals.
