Virgin's 25 year anniversary ad - still red hot

This is the first 80s throwback ad which I think works very well, even down to the retro styling of the ad direction. Brings back a lot of memories. Top marks all round.

But why can't I find a decent quality version on YouTube from Virgin themselves? Why only have it on Virgin's microsite with no share/send buttons? You can't even watch it on Facebook... Considering Mr Branson's dalliances with Twitter and social media this seems like a real faux pas, no? Or does Virgin not want to have it discussed/forwarded on? In which case, why have a dedicated microsite, and a pretty effective PR operation to support it, but no obvious campaign to generate online talkability/distribution of the ad. Curious. I'd have loved to have the brief to generate coverage for the ad and the red hot campaign...

Anyway, excuse the quality. But do admire it at the same time.
