Burger King hired advertising agency Crispin Porter + Bogusky (CPB) in 2004 to help boost declining sales. CPB launched unconventional viral marketing campaigns like Subservient Chicken, where visitors could give commands to a cartoon chicken, garnering over 20 million views in 10 days. Their next campaign, CoqRoc, promoted Chicken Fries by pretending to be a metal band, though it risked alienating non-teen audiences. CPB's campaigns successfully generated buzz but faced some criticism. Overall, the viral elements boosted awareness but integrated further with TV and additional media could have more effectively reached all customer groups.
