CP+B experienced rapid growth in the late 1990s and early 2000s, achieving notoriety on the strength of work for Burger King, BMW MINI, and anti-smoking campaign TheTruth.com. Sally Hogshead worked for the company at this time, and opened Crispin Porter + Bogusky's Venice, California office.

They are known for using viral marketing techniques, including the Burger King Subservient Chicken and Whopper Sacrifice campaigns. In September 2008 the agency created a television spot for Microsoft featuring Jerry Seinfeld and Bill Gates that received negative media attention. The 'I'm a PC' campaign that followed fought back against Apple's Mac vs. PC campaign and contributed to Windows 7 becoming the fastest selling version of Windows to date.
