Travel companies now have a lot more things to worry about. Tackling only their direct competitors isn't enough any more. The threat from indirect competition is extremely high. And this is evident from the work by non-travel companies like Apple (primarily a digital electronics company) and Google (primarily a search engine company) in travel industry. For Apple, it started with their Siri product, they have merely penetrated into travel industry.
In July 2012, Google launched what we call a "masterpiece" - Google Now! It's a super intelligent personal assistant for Google's Android. Google Now performs actions that are similar to what Siri does, but Google Now is significantly superior in terms of use cases handled and the functionalities supported. In our view, Google Now and Apple's Siri cannot be compared at all.
