Each week, advertisers allocate billions of dollars to deliver their messages via commercials featuring sight, sound, and motion.

To measure the brand impact of television, 4C analyzed social-media engagement across Facebook and Twitter during May. Advertisers are ranked according to total ad minutes aired in each category.
