Facebook CEO Mark Zuckerberg has stated in 2010 that ``We have not once bought a company for the company. We buy companies to get excellent people... In order to have a really entrepreneurial culture one of the key things is to make sure we're recruiting the best people. One of the ways to do this is to focus on acquiring great companies with great founders.''
