Karsa Flash Payer offers a way for content creators to monetize their online video using a bait and switch model in which payment is only requested mid-viewing, once the user is already hooked. The service was developed by UK-based Steven Carroll, the guy behind Documentary-film.net, which came very close to entering the Deadpool after he found it difficult to generate enough revenue to cover the hosting and bandwidth costs of the site.
Instead of forcing the viewer to commit to paying up front for content that they may not yet consider worth their cash, Karsa allows for it to be viewable for free for a set amount of time, after which the video pauses and the user is prompted for payment. Once paid-for, playback of the video can be resumed.
