Google's YouTube helps the real estate market

Other than Sequoia Capital, there was another investment firm that invested in YouTube -- Artis Capital Management. This is according to a report in the San Francisco Chronicle.

However, there is no indication of how much Artis made when Google bought YouTube for $1.65 billion, but it was enough to allow its president, Stuart Peterson, to buy a $20 million house.

The house was owned by the famous tennis legend, Andre Agassi. Apparently, he has been trying to sell the place for the past few years. The main house -- which is about 10,500 square feet -- is on a 3 1/2 acre lot.

Of course, the house is decked-out with a tennis court and a home theater, where Peterson can watch his YouTube videos.
