MOBILE PHONES TO REPLACE TV AS PRIME AD MEDIUM Mobile phones will replace TV as most important medium, says ad agency chief By Gary Silverman in London Published: April 7 2005 03:00 | Last updated: April 7 2005 03:00 Mobile telephones and other wireless communication devices will soon become the most important medium for advertisers to reach technology-savvy consumers, one of the world's leading advertising executives said yesterday. The forecast by Andrew Robertson, chief executive of Omnicom's BBDO advertising agency, the world's third-biggest, underscores the uncertainties facing advertisers in developed markets as they shift from their traditional dependence on television.
