Commodore Advert - September 1981

Commodore PET: Choosing a Computer Made Simple
The PET had been around for nearly five years by the time this advert is published, and so it's less of a case of advertising the hardware (which hasn't really changed much, apart from a bigger screen, updated BASIC and more memory) and more of a case of advertising the software available for it, the uses it could be put to and the support you could get for it. Software was perhaps becoming the more important differentiator by now - witness the release of Visicalc influencing sales of the Apple II (and effectively saving Apple) - often sales of machines would live or die by the number and diversity of titles available, and bigger companies like Commodore would invest money to write enough of their own to make sure they had all the major applications covered .
