In January, it was announced that for the first time, Microsoft's Bing search service finally went past Yahoo to become the US's second most popular Internet search provider. This week, Comscore revealed the latest Internet market share numbers for April 2012 and saw both Bing and Google extend their market share leads on Yahoo.
The results show that Google had 66.5 percent of the US Internet market, up from 66.4 percent in March 2012. Bing also went up last month, to 15.4 percent, compared to 15.3 percent in March. Yahoo had 13.5 percent of the search market in April, down from 13.7 percent.
Microsoft is still in the middle of a 10 year deal with Yahoo to provide the majority of the web site's search technology. If you combine Microsoft's numbers with Yahoo it means that Microsoft's search engine technology now controls 28.9 percent of US search results.
The Ask search network had 3 percent of the US search market share in April, while AOL's network held onto 1.6 percent. Both were unchanged compared to March.
Microsoft announced a major revamp of Bing a few days ago which, among other things, will see Facebook posts added to Bing's search results.
