FORTUNE — It will come as no surprise to anyone who watches a lot of television that Samsung has been spending a fortune on advertising — more, as Asymco’s Horace Dediu never tires of reminding us, than Apple , HP , Dell Microsoft and Coca Cola combined. But the report that Ad Age issued Monday puts the U.S. portion of that spending in some perspective. Topping its list of the U.S.’s 100 fastest growing ad spenders for 2012 was Samsung at 58%. Number 2, if you are keeping score, was Amazon AMZN , which spent — dollar for dollar — 25% more than Samsung. Apple didn’t make the top 10.
