World’s Big Five
What are the world’s “big five” traditional ad agencies? The big five are:
- WPP (includes Ogilvy, Young & Rubicam, GroupM, etc.)
- Omnicom (includes BBDO, DDB, TBWA, etc.)
- Publicis (includes Saatchi & Saatchi, Leo Burnett, etc.)
- Interpublic Group (includes McCann, Weber Shandwick, etc.)

The best TV show about advertising (in the 60s and 70s) and the “Big Four” in particular is “Mad Men”. “Mad” stands for “Madison Avenue” where many of these agencies had their offices, but could also refer to the mad working style (pitches) that these people had.
