The BBC describes Doctor Who as the most poular ongoing series it has ever made. More than 40 years after the first episode aired, the cult series returned to the small screen with a huge budget and with acclaimed writer/producer Russell T. Davies at the helm. A new generation of viewers adopted Christopher Eccleston as their Doctor, just as previous generations embraced William Hartnell, Jon Pertwee, Tom Baker, and Peter Davison. The unofficial guide, covering every aspect of Doctor Who broadcast to date, details not just the 700-plus episodes of the TV series (1963–1989) but also the radio serials, TV movie, charity specials, and internet-broadcast animated serials that have been transmitted while the television series has been off the air. Providing transmission dates, trivia, opinions, and commentary, Who's Next will inform and entertain the series' newest viewers as well as providing long-term fans with a fresh and indispensable set of critical perspectives.
