Continuing their 20 Year Anniversary celebrations, famed game developer Blizzard Entertainment have released a new retrospective video. The 48 minute long clip features interviews with senior Blizzard developers and offers an in-depth overview of the entire company from 1991 through to present day. Topics discussed include how the company originally came together, their name changes and every original game from Rock n' Roll Racing through to StarCraft 2.

We haven't been sent a local download option for this one yet, so you'll have to stream it over on Blizzard.com and it's a 600MB streaming video file, but it's well worth it for anyone who has ever enjoyed a Blizzard game.
