This was an inevitable rise of online advertising by Google Inc.'s that pushed the stock to record levels this year.

The Mountain View, Calif.-based company's stock traded at a low point during March, at $331.55 on the NASDAQ. But then Google managed to hit expectations in the following two quarters. The company maintained a huge berth as leader in the U.S. search market all through the year and had 49.5 percent of searches during November.

This year Google extended its advertising services beyond the Internet to radio and newspapers. After closing for YouTube Google hit the high share of $513 during November.
