At fifty issues per year, 2000 AD will overtake Buster and War Picture Library in 2018. It’ll overtake Bunty in 2021, and Comic Cuts in 2036. In 2053 it’ll move into third place, displacing The Dandy. And if both The Beano and Commando cease publication right now, 2000 AD will take the top spot around 2076… just in time for its 100th birthday!
[Update 9 May 2018. Turns out that this chart wasn’t entirely accurate: Buster had only 1902 issues, not 2080, so 2000AD was actually in eleventh place. See the updated chart for much more info!]
