Urban Entrepreneur: Innovators -- (career book, nonfiction), sample page:

​       Here’s another way to look at it: an invention is something brand new. It’s a product that didn’t exist until someone created it. An innovation is a new use for that product.

       Let’s check out a more modern example. In the old days, people only used to listen to music at home. They would listen on a record player or on the radio. Then there was a remarkable series of innovations. These innovations allowed us to take some of our music with us anywhere we went. There were cassette decks in cars. Walkmans also became very popular (they were portable devices that played cassettes or CDs).

       The next innovation was the most important one in history. As you can probably guess, it was the iPod. This little device made it possible to carry around all our music.
Let’s stay on the subject of entertainment. You probably don’t spend much time thinking about the television (not what shows are on, but the TV itself). Here is a fact you may not know: It wasn’t until the 1950s that TV sets became common items in most homes. That was after World War II. Many people lived in big cities and times were good. For the first time, average people could afford to buy a TV.

​       The 1950s may seem like a long time ago, but ask your grandparents—some of them will tell you that they grew up without television. How would you like to have no television? (or video games, cell phone, or Internet). Life wouldn’t be nearly as fun, that’s for sure.
