In the great outdoors, billboards in clear view mean money for Clear Channel Outdoor Holdings. The company is a leading display advertising operator, with about 820,000 properties in some 45 countries. Besides billboards, Clear Channel Outdoor Holdings sells advertising on buses and trains and on "street furniture" such as bus stops and information kiosks in metropolitan markets. The company sells advertising space in airports and malls and on the sides of high-profile buildings, and also creates displays that feature video and moving parts. CC Media, which also owns #1 radio broadcaster Clear Channel Communications, controls the company.
