Google's executive chairman Eric Schmidt has denied that the search giant fixes its search results in order to promote its own websites and services.
Schmidt told the Senate Judiciary subcommittee on anti-trust, which is looking at whether Google abuses its market position, that the firm is not “cooking anything”.
“May I simply say that I can assure you we're not cooking anything,” the Telegraph quoted Schmidt, as saying.
“Google does nothing to block access to any of the competitors and other sources of information,” he added.
When asked whether Google was a monopoly company, Schmidt said the search engine giant was “in that area”, adding that it recognised it had a special responsibility because of its market power.
“We get it. By that I mean, we get the lessons of our corporate predecessors,” Schmidt added in reference to software giant Microsoft, which faced years of anti-competition investigations and subsequent fines.
Concern over Google's domination of the internet has grown as the company continues to expand into other internet areas, such as its own price comparison website and buying US mobile phone firm Motorola Mobility.
