I saved this article from 1997. I should have wrote down the magazine; I think it was the Globe tabloid magazine.
The top 100 inventions.
Note the car in 23rd place, slightly above the bicycle (at # 25).
I agree with the radio being in the top 10. For many years, it was a good way to get up-to-the-date news. Not surprisingly both the computer and the internet are also in the top 10.
I think television (#75) should place much higher. It has the benefit of a radio but with a picture. Good for getting news and for enjoyment (movies, TV shows, videotapes, DVDs, video games).
