Is it true that there were recently two major polls about Doctor Who?

Yes. The American TV Guide asked readers what they thought was the best science-fiction programme of all time. Doctor Who finished second with about 7500 votes, 150 behind the winner, Babylon 5. Unfortunately, this was an extremely unscientific poll, with fans able to vote multiple times, and hence is probably not a good indication of the actual popularity of the programmes involved.

Meanwhile, the BBC's Radio Times ran a poll asking readers if they'd like to see Doctor Who back on television. While final tallies aren't known, the polltakers did confirm that the "Yes" side won decisively.
