The Federal Trade Commission closed its investigation against Google for antitrust violations Thursday.

For almost two years, the FTC has been investigating Google for various business practices, primarily concerning how the company displays search results. The FTC has also looked into Google's practices regarding technology licensing.

Google has been criticized for promoting search results for its own services over its competitors.

Many of Google's competitors wanted Google to change its alogorithm for search results, however, the FTC did not find that its practices for search results violated American law, said Jon Leibowitz, the chairman of the FTC at a press conference.

The trade agency investigated extensively Google's 'Universal Search' product, which prominently displays Google services that fall into certain categories, like shopping or local. But the agency found that the algorithms for 'Universal Search' could be "justified as innovations that improved Google's product and the experience of its users," therefore, it was not in violation of any law.
