So "early on", we're talking about 1960s/1970s advertisements for mainframes of IBM, DEC, VAX, Burroughs, etc and the 1980s ads for personal computers like IBM PC (original), Apple IIe, Commodore 64, Radio Shack TRS-80, etc.
If we want to blame early period "marketing" for women's lake of interest in computer _programming_, we have to also explain the counterexample of early marketing for PacMan, DonkeyKong, Missile Command not having the same decades long suppression of female computer _gaming_. The video gaming magazines and its ads in the 1980s/1990s were heavily male-dominated. (Arguably, the videogames ads were more male-themed than mainframes' ads. The videogames' ads often had abundant cleavage and skin. The mainframe ads did not.)
>, and I would be shocked if there isn't a strong correlation between interest in video games and computers in general.
Video games are marketed more to males but that didn't stop females from participating in large numbers.[1]
Why would "male marketing" dissuade females from computer programming but at the same time, it doesn't affect computer gaming?
