Stephen Fry said 3D TV is "the next most exciting chapter in television history" and is sharing his passion with the public.
The comic and self-confessed technophile has produced a short-film - in association with Sky - which takes a wry look at 3D TV and how it works, without the jargon.
Fry said: "3D TV in the home is going to be the next exciting chapter in television history and I'm delighted to be able to offer a little clarity on the subject."
The QI presenter - famous for his encyclopaedic knowledge on just about any subject - seeks to enlighten and dispel the myths about 3D, ahead of the launch of Sky's 3D channel on October 1.
Sky 3D, set to become Europe's first 3D channel, will show live sports, films and documentaries to the millions of Sky+HD customers at no extra charge.
Fry added: "2010 has been a triumphant year for new and innovative technological developments, which is great news for all of us, not just technophiles like myself."
Brian Lenz, Sky's director of TV product development, said: "Stephen's guide is a great, simple 'one-stop' video that will help provide some understanding around 3D television and show viewers how simple it is to become 3D ready".
Stephen Fry's guide to 3D TV is available to watch on www.sky.com/3D.
