Wonder Woman is a household name, we have no clue who Captain Marvel is
I will say this...... Household to who?
Kids born in say 2003 to up last year when WW movie dropped probably had no idea who she was?
Where was she at really in any media? And lets just say by chance "well my mommy and daddy told me" how far does that really reach?
Now do they know her now? Sure and that can be easily done for that same demographic and others for CM. Disney (like they did with IM, and Guardians, and Antman and Black Panther) have a full year to educate people on who CM is... and hell they been already started with the kids via the Avengers cartoon show.
I'm grown ass 80's baby like most of the cats on here... but lets not pretend commercially WW was out there as a consistently equal as some of the other characters thats been crossover hits for years.
