Dentsu

:No advertising agency dominates its market as comprehensively as Dentsu, which controls more than 40% of all mass media advertising in Japan, and has a staggering portfolio of more than 6,000 clients. Until recently, Dentsu's influence outside Japan has been limited to say the least. But since 2000, the giant has begun to spread its wings, becoming one of the principal backers of the newly expanded Publicis Groupe in a concerted bid to increase its share of Western advertising budgets. Advertising Age ranked Dentsu as the #5 ad organisation worldwide in 2004 with revenue of $2.9bn. Source
==introduction==
:Dentsu is the largest advertising conglomerate firm in Japan (controlling over 30% of the total market by revenue and an estimated 40%-50% of commercial airtime on Japanese television) and one of the largest advertising conglomerates in the world. It operates in 27 countries. 95% of revenue currently comes from Japan.
:Like Havas, it began as a news service and advertising agency. In line with Japanese and major overseas competitors the group's services include media and event planning, market research and public relations. It also has large-scale printing, data processing and systems integration, music publishing, exhibition, film and other operations.
:It has alliances with WPP (eg a partnership with US-based Young & Rubicam) and a stake of around 15% in Publicis. Source
