On this day three decades ago, Sony's original blue-and-silver Walkman went on sale in Japan, launching an era of personal, portable music and generations of oblivious subway riders and pedestrians.
The first Walkman, called the TPS-L2, cost 33,000 yen (roughly $150) in Japan and didn’t make it to the U.S. until 1980. In case you forgot, the original cassette-playing device had some quaint features, including a pair of headphone jacks that allowed two people to listen simultaneously and a "hotline" switch that activated a microphone to pipe in ambient sound instead of music.
For the price of a 1979 Walkman, you can get a Walkman Video MP3 Player today, with four gigabytes of memory that stores up to 40 hours of music and 10 hours of video, capabilities that were inconceivable during the disco era.

Companies marketing their products and services are going green, whether they're selling cars, computers or televisions. One need look no farther than last week's Consumer Electronics Show (CES) in Las Vegas, where new products carted out invariably had a smaller carbon footprint than anything introduced a year ago. Meanwhile, products and services that aren't using enough recycled components or that hog too much energy are taking a lot of criticism.
The latest green brouhaha comes to us courtesy of a Harvard University physicist and Web juggernaut Google over the how much carbon dioxide the company's data centers are pumping into the environment each time consumers launch searches on it.
A typical search generates about seven grams of carbon dioxide, according to Alex Wissner-Gross, due to the amount of computing power required to scour the Internet for search results as quickly as possible. Wissner-Gross's research indicates that viewing a Web page generates about 0.02 grams of carbon dioxide per second, a number that jumps to about 0.2 grams of the greenhouse gas per second when viewing a Web site with complex images, animations or videos (all of which require enhanced computing power and network bandwidth to function properly), the Times of London reported yesterday.

If you're planning this holiday season (perhaps even today) to become one of the tens of millions of people in the U.S. to buy a video game system, you may want to consider how the purchase of a Nintendo Wii, Sony PlayStation or Microsoft Xbox will impact your carbon footprint (or, at very least, your electric bill).
