BtoB Online reports that TNS Media Intelligence released figures showing that marketers spent $141.1 billion in the U.S. in 2004, up 9.8 percent over the previous year. The internet grew the fastest, as is customary, it's growth rate reaching 21.4 percent. Outdoor advertising came a very close second, growing 20.1 percent, followed by syndication (up 15.8 percent) and cable (up 13.8 percent). Procter & Gamble and General Motors again topped the list of spending marketers, approaching $3 billion each. Time Warner came in a distant third, although its media properties typically book a great deal of barter between themselves, making that company's true expenditures harder to calculate.
