We don't usually call printed advertisements commercials. Commercial usual means an advertising in a radio or television setting. Even advertisements in a movie theater don't tend to be called commercials.
There is a Color TV-Game commercial supposedly from 1977 (not totally clear whether this is the year of the ad itself or the year of the product launch) [1].
The commercial features the first two machines. There's many plausible reasons for this including, most prominently, that the third might not have been released yet.
So, where's the link to archive.org?
