on Wednesday announced a revamp to its search service and a slew of new features.
Called "universal search," Google's new method will incorporate results from a variety of new categories such as video, books, images and local into the search giant's traditional display of Web page search results.
Users searching for the term "I have a dream" -- a reference to Martin Luther King Jr.'s famous speech, for example -- will be shown Web results as well as video clips.
The new feature will take advantage of the various different types of content -- from video through the company's YouTube acquisition, and books through the company's ambitious plans to scan millions of titles.
The move is important because Google is the world's most used search engine, and it carefully considers changes to its search methods. Search advertising makes up virtually all of the company's revenue.
Google had first thought about tying together search results in 2001, said Google vice president Marissa Mayer, but did not have the resources to pursue the idea then.
The company also announced a navigation link that will allow users to drill down into specific categories as well as a toolbar that allows them to toggle between different Google tools.
Shares of Google were up $8 to $466 midday.
