SEATTLE (AP) – Orange Cabs says its test of Wi-Fi service and digital screens in 10 taxis was a success. It has won permission from Seattle regulators to put Internet access and screens in more cabs. During testing last month the Seattle Digital Signage company screens showed news headlines, traffic maps and advertising. The company says it's developing more content to be displayed to taxi passengers. AP-WS-03-11-08 1218EDT
