There are three dozen companies that spend over $1 billion per year on advertising. If you are a sports fan, you might assume that Anheuser-Busch is the largest advertiser in the world, though it actually comes in the $21 spot with an advertising budget of $1.5 billion. The giants in the industry have been AT&T, Comcast, Verizon, and General Motors, with budgets between $2.5 billion and $3 billion. The true giant in the sphere is actually Procter & Gamble, mostly because it has a diverse constellation of brands that need constant brand equity upkeep, and P&G spends $5 billion per year raising product awareness for customers. It spends over $2 billion per year on TV ads.
