i think.. google would not want to sell their company..to anyone... because....their are pretty much comfortable on how they are earning BIllions of dollars...take note billions...
When they went public, the founders of Google basically set it up so no one could ever take over decision-making power of the company. All of the shares owned by the founders have ~100x as many voting rights as all other shares. So even if you buy 51% of the company, you still wouldn't get the normal majority shareholder powers.
