Guess what the number one, most downloaded TV show on iTunes was last year. Glee? Nope. Mad Men? Not quite. It's Doctor Who. Want to read a book about him? They have published hundreds, and dozens more hit the shelves every year, not to mention three magazines devoted to the show. Want a replica Sonic Screwdriver like the Doctor uses? There's that and more: action figures, TARDIS USB hubs, play sets, posters...the list is endless. And it sells. Even Muskogees own Hastings stocks quite the supply of Doctor Who items (and gets quite a few exclusive-to-the-chain items!). Late Late Show host Craig Ferguson has long been an outspoken advocate of the program, and everyone from Tom Hanks to Stephen King to Bob Dylan counts themselves as friends of the Doctor. South Park has even been known to slip references into the background of episodes.
