Producer Damon Lindelof was informed of the award on 1 April and thought someone was playing a prank on him for several hours before realising it was the real deal.
This year SF got a bit of a double whammy. Lost won an award recognising its merits:
"Breezily mixing metaphysics, quantum physics, romance and cliffhanger action, the genre-bending series about a group of air-crash survivors on a mysterious island has rewritten the rules of television fiction."
Whilst the animated show Avatar: The Last Airbender, which came to an end last year, was also recognised:
"Unusually complex characters and healthy respect for the consequences of warfare enhanced this American-made, anime-influenced martial-arts adventure."
