From PC World:
People in the U.S. use the Internet for more everyday research than any other medium, a fact proven by the 55 percent year-on-year surge in online searches in December, according to market researcher Nielsen/NetRatings. And Google remained the most popular place for Americans to search cyberspace in December.
The number of online searches in the U.S. soared to nearly 5.1 billion searches in December from 3.3 billion a year earlier, despite just a slight uptick in the total number of Americans connecting to the Internet, according to Nielsen/NetRatings.
