Television is a powerful advertising medium, providing emotional resonance and scale to ignite conversations and connect consumers with brands. Each week, advertisers allocate billions of dollars to deliver their messages via commercials featuring sight, sound, and motion.

To understand which brands are most active on TV, we rank the top UK advertisers using 4C’s Teletrax technology, the largest global TV monitoring network. Advertisers are ranked according to total ad minutes aired across several different categories including network, daypart, and programming.

TV ads featuring a blue rabbit and highlighting O2’s live entertainment experiences  helped drive social engagement for the telco company in March.
