The Internet is the fastest growing in terms of ad spending of all the media in U.S. throughout 2011, according to eMarketer's estimates.

The U.S. online ad spending in 2006, grew with a nearly 35 percent, while the growth rate dropped to 26.8 percent this year. Although it is dropping and stabilised by 2011, the annual online growth still exceeds 10 percent and tops those of all other media.

With the Internet taken out, other media grow very poorly throughout 2011 – the annual growth of total media without Internet is even less than one percent, except for the 2.4 percent in 2006. The overall growth of U.S. ad spending in media fluctuates between two and four percent from 2006 to 2011, eMarketer reported.
