Clear Channel Outdoor's comprehensive range of cutting-edge properties includes Clear Channel airports, Clear Channel malls, Clear Channel taxis and its spectacular sign division, Clear Channel Spectacolor.

"Technology is changing the fundamentals of the advertising industry; and as society becomes increasingly mobile, Clear Channel Outdoor is positioned to maximize the potential of these technological changes," said Hudes. "We will focus on creating new products that are more flexible and effective in enabling advertisers to deliver more timely and relevant information to consumers. The end result will be to increase the value of out-of-home media in the advertising landscape."

Hudes will be based in northern California, in the company's Bay Area office. Prior to joining Clear Channel Outdoor, Hudes was president and chief operating officer of AdSpace Networks, Inc. Under his leadership, the company became a leading builder of digital media networks for advertising and promotion in public spaces, said an official release.

According to a media report, Clear Channel Outdoor has an annual revenue of more than two billion dollars and hundreds of thousands of outdoor signs worldwide. The company's parent, San Antonio-based Clear Channel, in February said its outdoor advertising and concert promotion businesses offset weaker radio revenue in the fourth quarter.

The company soon hopes to come out with remotely operated digital billboards on roadways which will give advertisers the opportunity to customise their messages according to the time of the day, area demographics, language and location.
