At 7pm on March 26, 2005, Doctor Who returned to BBC One, with Christopher Eccleston and Billie Piper. It's been nine years since the Ninth Doctor grabbed Rose Tyler's hand in the basement of Henrik's and told her to "Run!", so join us for a look back at Series One of Doctor Who. Fantastic!

New to Who? Never seen an episode? Or just curious about where it (re-)started? The first episode of the 2005 series Rose is a great jumping-on point, and to help, we've produced a guide to the episode for new fans as part of our Getting To Know Who series. (There's also a guide to his last adventure too, but - you know - spoilers.)
