With all their different ventures, Google is doing very well. So well, in fact, they apparently have doubled the amount of profit they are earning. For a company based on a free search engine, they've come a long way:
The internet search engine said it had net income of $721m, or $2.33 per diluted share, up from $343m a year earlier. Wall Street had expected earnings of $1.94 per share.
Google is still an advertising company at its heart, and receives nearly all their revenue from it. As the Internet continues to be made more easily available, it's unlikely Google will fall anytime soon.
