Note: More information on the publisher's blog. Overview of the fondly-remembered early 70's British comic Countdown (later renamed TV Action), which featured comic strips from a number of popular 60s/70s TV shows — including Thunderbirds, The Persuaders, Hawaii Five-O, and of course Doctor Who (hence its inclusion on this site). Although it was a weekly comic, the publication spawned a series of 3 annuals, which are also listed on this site: Countdown Annual 1972, Countdown for TV Action Annual 1973 and TV Action Annual 1974.
