• Through the Limelight content delivery network, Brightcove will support distributing broadband video in a variety of formats (including Adobe Flash streaming video, Windows Media video, and MPEG-4) to a wide range of Internet-connected devices, including PCs, handheld devices, and home-networked TV sets.
• By working together, Brightcove and Limelight will accelerate the adoption of innovative Internet TV business strategies including both pay media sales and the next-generation of broadband video advertising--providing aggregated, targeted audiences to advertisers, great experiences for consumers, and new revenue opportunities for content owners.

"We chose Limelight Networks as our strategic partner for content delivery because they share our commitment to enabling innovative business models and their global delivery infrastructure has the proven capacity, reliability, and performance that media companies, web publishers, and consumers are demanding from Internet TV," said Jeremy Allaire, chief executive officer at Brightcove.
