In order to document how well viewers learn health information from entertainment television, the Foundation worked with writers at Grey’s Anatomy to embed a health message in an episode, and then surveyed viewers on the topic before and after the episode aired. The study included three national random-digit-dial telephone surveys of regular viewers of the show, conducted one week before, one week after, and – to test retention of the information – six weeks after the target episode aired.
