The Advertising Industry The advertising industry is dominated by three huge advertising networks, which offer their services throughout the world. Gross income of the three leading agencies is twice as much, as the one of places four to ten. Table: World's Top 10 Advertising Organizations 1999 (figures in millions of U.S. dollars)

On the other hand the three biggest advertisers only spend about US$ 2 millions less than places four to ten together. Whereas money spent on advertising in traditional media comes from very diverse categories, companies offering computer hard- and software, peripherals or Internet services mainly pay for on-line advertisements.
