ParrottBoy: The study sign is Sherlock. The first episode was titled A Study in Pink.
chokkie: I'm not sure about Dragon's Den. The Levi Roots sign could also relate to his cookery show Caribbean Food Made Easy.
andrewc: Thanks for the Corrie reference, I'd missed the Newton & Ridley sign. I think the werewolf might be Being Human; the shield with three trees on is The Inbetweeners, it's the school crest; and the woman in blue, if you mean the one on the far right, is from Ripper Street. Like you I'm also stuck on the sobriety chip, the map markers, the police badge, and the cctv camera.
I'm also stuck on the symbol next to Harry Hill, the mammoth ( I assume it relates to one of the BBC's Walking With... series, but can't be sure.), 1.8288m (That's the equivalent of a fathom, which was the working title of Surface, but seems a bit obscure to me.), NAOMISWED (There was a character in the 90210 reboot called Naomi, and one of the plotlines concerned her wedding.), and the helicopter (I'm now wondering if both it and the 'Big C' are one clue, otherwise I've got 51!).
