Google's travel plans

[Commentary] The Justice Department must determine whether Google's purchase of ITA could substantially reduce competition. These assessments are fact-intensive and often made based on the merger's impact on a narrowly defined market. Justice should not confine its review but should also consider the implications of allowing an already formidable Internet power to continue to expand its reach and consolidate its grip over a range of Internet commerce. This does not necessarily mean that the deal should be quashed. Google gained prominence - and dominance - by providing innovative services to consumers and businesses alike. Its purchase of ITA may very well bring the same benefits to online travel search. But regulators must review the deal closely to ensure that Google's vast power and reach do not unfairly hinder others' ability to compete or deprive consumers of innovations not yet imagined.
