• The top selling Blackest Night issue was Blackest Night #1 with sales of more than 200k copies. The worst selling Blackest night title was REBELS #11, with sales of just over 30k.

• DC Comics charged $2.99 for issues of both Green Lantern and Green Lantern Corps during the Blackest Night event. Had they charged $3.99, like they did most of the other related titles, DC would have raised another $1.6 million.

• In November, DC Comics began publishing a two issue Blackest Night story in six existing titles (Outsiders, Adventure Comics, REBELS, Booster Gold, Doom Patrol and Justice League of America). Fans that purchased the first of the two issues were given a free promotional lantern corps ring. Total sales for the second issues in these six titles fell by more than 120k copies, or 30%.

• DC Comics offered promotional rings that represented each of the various lantern corps. The set of eight, which was free with purchase of the titles listed above, will cost you $15 to purchase on Amazon today.
