The Walkman Lives!

Older music fans became sad over the weekend. A rumor spread that the Sony company had stopped manufacturing the Walkman cassette player. Unveiled on July 1, 1979, in Japan, the Sony Walkman was the first inexpensive, portable music-album player. It was hugely popular in the years when many people listened to albums on cassettes. As CDs took over, and then MP3s, sales of the the cassette Walkman dropped. But if it weren't for the Walkman, the iPod may never have been invented.

On Tuesday, those fans got some good news: Sony was only stopping sales of the Walkman in Japan. The product will still be available in the United States and elsewhere around the world.

In the past 31 years, approximately 200 million Walkmans have been sold. On average, how many is that per year, rounded to the nearest whole number?

That's about 6,451,613 Walkmans sold per year.
