What are the top 10 biggest December Console sales ever?
I'll do you one better. Here's the Top 25 (home consoles only):
The Top 10 is dominated by the Wii, PS2, and PS1. I expanded the list to 25 to get some current-gen years in there. Between November siphoning off some holiday sales from December and the PS4 & XBO being relatively close competition (the closest we've seen since the 16-bit era) there haven't been any historically huge Decembers yet this generation. The Switch could change that, though. It ought to bust into the Top 10.
And for the hell of it, here's the Top 25 Novembers just to show how big that month has gotten in the past decade:
The Top 10 Novembers list is completely dominated by sales months from this decade, with only the Wii's extraordinarily huge performance in Nov. 2008 standing above them. The only other sales month in the Top 10 that was from 2010 was the PS2's Dec. 2002 performance. And the biggest November performance from before 2000 was the PS1's showing in Dec. 1998 way down in 19th place.
Just goes to show you how all the massive Black Friday deals that emerged early this decade have impacted the balance of holiday sales in the U.S.
