The bad news just doesn’t seem to send for Yahoo! New research from comScore concludes that for the first time, Google has overtaken Yahoo as the most-visited website in the U.S.

Google reached this pinnacle in the top 50 U.S. websites, with an audience of 141 million visitors according to data from comScore’s monthly analysis. Yahoo sites ranked second, with 140.6 million visitors, closely followed by Microsoft sites with 121.2 million visitors. Other websites such as Superpages and CareerBuilder both jumped ahead eight spots to come in 18th and 30th respectively according to comScore.

"April was a very active month. Google took the top property position, thanks to continued search growth and rapid growth at YouTube," said Jack Flanagan, executive vice president of comScore Media Metrix, in a statement.

"The return of the network television programs after the writers strike sent fans to a variety of sites to get information on their favourite shows, catch up on episodes they may have missed, get refreshed on plotlines, and to stream new episodes."

As people U.S. rushed to meet the April 15 deadline to file their taxes, a number of tax-related Web sites recorded increased numbers of visitors. For example, 23.4 million visitors logged on to IRS.gov, up 35 percent from March and Intuit.com's traffic rose 11 percent from March to 13.3 million visitors.

"The significant traffic growth at tax sites, which began in January, reached a crescendo by the tax filing deadline on April 15 as taxpayers sought information, forms, and online filing facilities," Flanagan said in the statement.

So Google has done it again. It is getting closer and closer to a complete takeover of the search engine industry and we may even find one day, Google being the one and only as more and more people use the rapidly expanding future technology driven search engine.
