2. Google

After God, people ask Google to solve their problems! So for the importance gained, this internet giant is specialized in online advertising, cloud computing and most of the internet-related products. Though Google has attained heights in selling ads on internet, it is now putting mighty challenges to Microsoft, Amazon and other fellow competitors.

Recently, the release of Chrome OS devices and Google Shopping Express has created a boom in the Enterprise and IT industry. The market capitalization for Google is $398.37 billion.

3. Microsoft

One cannot imagine a world without Microsoft windows, office suit and the internet explorer web browser. It is the world’s largest software making company. Even though Microsoft stopped selling Windows XP PC’s since 2010, the company will bag millions from the product.

With the acquisition of Nokia and appointment of new CEO Satya Nadella, the company smells the new breeze in sales. Microsoft still stands high with a market capitalization of $364.12 billion.
