commodore's ads in the US were colossally stupid - the only thing I ever saw approaching "good" advertising was a four page spread in Time magazine that showcased BB King, Richard Jarvik, aaannnnnd...now I can't remember who else, but they basically did little blurbs about how indispensable the Amiga was to them - they reminded me a lot of Macintosh ads of the day.
The TV commercials, however, were execrable. Search for them on Youtube if you don't believe me.
In the overall C= didn't advertise the Amiga because one, I don't think they knew what to do with it and two, I think all they'd wanted in the first place was a way to leverage themselves against Atari (remember, Tramiel had just jumped ship in 1984) and siphon off potential ST sales, which it did admirably, at least here in the States. I knew exactly two guys with STs but a liberal amount of Amiga users.
