Counts are the event sponsor lists, newsletters and podcasts where Ad Almanac has recorded the company. Exhibitor and partner listings don’t count. Ranked by the company’s smallest channel, so breadth beats one big one. They don’t measure spend, and a company missing here may still buy a channel we haven’t recorded.
