U.S. Internet ad spending is now on pace to expand 13.9% to $25.8 billion, according to revised estimates from eMarketer. The estimates, which are based on an "meta analysis" of various industry estimates and methods, also projects that U.S. online ad spending will expand 10.5% in 2011, which would be followed by double digit growth through 2004 when U.S. online ad spending will reach $40.5 billion.

"Increases in online spending will far outpace those for total media spending, which will inch up by 1.2% next year after rising 3% in 2010," eMarketer said in a released issued this morning. "In 2014, eMarketer estimates total media ad spending will be $188.5 billion, up from $168.5 billion this year. Faster growth online will help propel digital from 15.3% of total US ad spending in 2010 to 21.5% by 2014."
