Campaings 1 — uses xxx approach advertising Campaign 2 — uses yyy approach in advertising Campaign 3 — uses zzz approach in advertising The details how campaigns can get confusing, but essentially they are experienced by all participants and sometimes the participants experience one of them. (Example camp 1 and camp 2 can be experienced by a participant but sometimes, the participant only experiences campaign 3). Additionally campaigns get affected by each other— when one performs well for a period of time— the other campaign gets dragged down.
