Advertising Age's Media Family Trees

Published on .

Media power is top-heavy.

Aggregate net revenue of the companies shown on these pages represents 88%, or $160.8 billion of the $183.69 billion media revenue stream of the nation's Top 100 media companies. Specifically, full schematics are presented for 36 of the Top 100; attached to them are 10 other Top 100 companies in which they hold equity.

The Top 100 virtually control the market for national and local advertising.

These companies are highly interconnected as the dotted lines attest, abetted in part by an "outside" investor, Liberty Media Corp., spun off of AT&T Broadband last August. It holds interest in seven of the top 100 companies, though Liberty Media itself is not a media company by Ad Age definition.
