Advertisements on mobile telephones in Japan are set to triple by 2011, outpacing growth of advertising on the Internet, according to a study. By comparison, Japan's market for non-mobile Internet advertisements is expected to grow from 231 billion yen to 400 billion yen in the same period, according to the study released on April 16.
The growth comes after Japanese telecom operators last year equipped phones to search online by keyword, allowing advertisers to post related links in a revenue-generating model pioneered by Internet giant Google.
