     By 2010, spending on Internet advertising will account for 10% of total US ad dollars, according to

"The Changing Face of Advertising in the Digital Age" from Parks Associates.

     Roughly 21% of Internet users consider Internet advertising to be the most effective ad format. It has

gone beyond traditional media, such as newspapers, magazines, and radio.

     Behavioral targeting with a variety of sounds makes the channel attractive. "Because the Internet is an

interactive platform and offers rich consumer usage data, advertisers can improve their ad target ability

and achieve better results," said Parks Associates research analyst Harry Wang.

     Due to audience and media fragmentation (分裂), large companies and established brands will move

dollars from TV and other formats to the Web. Anheuser-Busch, Procter & Gamble, Verizon, and Wachovia

have already moved portions of their budgets to online advertising.

     "The Internet has changed the standard for the entire world, and traditional media have to respond by

making their media platforms more interactive and results-oriented," said Wang.

     The report was compiled (编写) from the findings of an Internet-based survey of 2,084 US consumers

in households with Internet access. The group includes 270 teenagers ages 13 to 17. The report contains

data from Parks Associates' consumer study "Digital Entertainment: Changing Consumer Habits".
