This past week in airports around the world, travelers waiting for Iceland's volcanic ash to clear the air could have used some entertainment. Soon, kiosks will be installed at 35 US airports, filled with digital films, television shows and music.

Customers will be offered the ability to rent or purchase programming which is downloadable to portable SD (Secure Digital) memory cards or USB memory sticks-their own or from a airport retailer.

The companies that developed the kiosk technology, NCR and MOD Systems, will install digital-download kiosks in InMotion Entertainment stores at 57 locations reaching 750 million travelers.

The video content is playable on Windows PCs, laptops, netbooks, and tablets, with additional consumer electronics device support planned for later this year.

Music tracks can be loaded onto any USB storage device and eventually onto portable MP3 players in seconds. Movie downloads often take less than two minutes - the time it takes to buy a magazine or newspaper.

The traveler has limited and inflexible options for entertainment, especially during layovers at gates. There are plans to expand beyond the initial rollout.
