[c3534l]

The fact that people were already reading about electronics in magazines they bought with their own money shows that people would have known what computers were regardless. Those advertisements only worked because the audience was already interested in computers. Those computers also already existed and the notion that no one would have used a computer if an ad didn't tell them to is absurd. Computers exist because they're useful and fun and they were purchased by people who wanted computers and were willing to seek out products they wanted.
