The BBC and Adobe has announced a strategic relationship that will see the BBC adopt Adobe's Flash Player software, allowing Mac and Linux users to use the broadcaster's iPlayer streaming video service for the first time.
The majority of the BBC's streamed video and audio content will also be moved over to this format to provide what it calls a "consistent user experience". However, at the time of writing, it hasn't confirmed that video for Windows users will be in Flash format. We're currently expecting clarification on this from Adobe.
