October 2017 had 7,028,651 units in the top 300 comics list, an increase of 192,398 units from last month. The premiere publishers accounted for 94.06% of the units in the top 300 comics this month while all of the other publishers with items in the top 300 accounted for 5.94% of the units. DC took 7 of the top ten slots with Dark Nights: Metal #3 topping the list with 158,698 units.
Marvel Comics placed 3,010,507 units in the top 300 comics and was up 40,565 units in the top 300 compared to last month and accounted for 42.83% of the total units for the top 300 comics. The new Legacy volumes started coming out this month and most of the new titles for Marvel fell into this category. The term "relaunch" seems to best describe these new volumes as most of them do not involve a radical new take on the character to warrant the term "retooling." None of them are tossing out the old continuity so calling them "reboots" would be inaccurate.
The titles launched after Secret Wars weren't "reboots," even though a number of them involved significant retcons. These distinctions might not seem important but they are more than mere semantics. The retcon (retroactive continuity) of establishing that Miles Morales somehow has been on the mainstream Marvel Earth along with Peter Parker attempts to keep the backstory of each Spider-Man intact while ambiguously implying they happened on the same world. This retcon doesn't disavow the previous adventures and titles while a reboot would. This distinction has a serious impact on story accessibility which in turn impacts sales. October saw new volumes of Amazing Spider-Man, Avengers, Black Panther, Cable, Captain Marvel, Deadpool vs Old Man Logan, Despicable Deadpool, Falcon, Incredible Hulk, Invincible Iron Man, Iron Fist, Luke Cage, Mighty Thor and Spirits of Vengeance.
Even with all of those new titles, Marvel only gained 40,565 units over last month. Part of that is due to the lost of 292,910 units from the Marvel Legacy one-shot last month. Sone of the relaunched titles got a second issue out in October such as Amazing Spider-Man which dropped by 52.12% and Despicable Deadpool which dropped by 63.96%. In both cases, the first of the Legacy numbered issues had multiple covers while the second has one or none.
