Yelp gets popular? Copy their info, shove Yelp to the bottom of the page and put Google Places and reviews at the top.
Groupon won't sell? Spend billions from other businesses to destroy them.
Twitter and Facebook innovate on search? Take their content, whine when they try and stop you then spend billions to prevent their growth and hopefully destroy them.
Apple working on a touchscreen smartphone? Spend billions from another business and copy everything you can, down to swipes and apps.
Need a smartphone operating system with Java. Take Java and use it for your own ends.
Need a location mapping technology and Skyhook won't sell? Spend billions from your monopoly profits and strongarm your partners and drive Skyhook out of business.

The list goes on...
