Bored on your subway commute? Try TV!

Atlanta will be the first city in North America to roll out TV and radio programming in its subway rail cars. Each of 230 cars will be fitted with 15-inch flat screens showing local news loops and radio transmitters offering music in three formats: top 40, jazz and R&B. Content stays fresh (so fresh!) via software on the trains that downloads new programming when the trains pass through 'wireless clouds' en route. Any FM receiver will be able to pick up the TV and radio audio feeds inside the cars. In partnership with New York-based media firm The Rail Network, the Metropolitan Atlanta Rapid Transit Authority (MARTA) stands to rake in about $20 million over the next decade by taking a cut of the ad revenue. And no wonder — it's hard to find a more captive audience.
