It seems as Google has been on a tear lately in their purchases of companies. It has been rumored for the last couple of days that their next target acquisition is going to be Feedburner. It looks like the price tag is hanging around the $100 million dollar range, but keep in mind this is just rumor. They (Feedburner) have been rumored to be for sale before, but rumors are like the wind, they come and go.

So if in fact Google does purchase Feedburner, their list continues to grow. They have made some interesting purchases in the recent past, when will their coffers run out? Taking a look back to when they purchased YouTube in October of 2006, they have amassed a $4.8 billion dollar (this figure represents those companies whose purchase prices are none) spending spree. The list includes:

• YouTube - $1.65 billion
• Endoxon - $28 million
• Xunlei - undisclosed amount
• Adscape - $23 million
• Trendalyzer - undisclosed amount
• Tonic Systems - undisclosed amount
• Marratech - undisclosed amount
• DoubleClick - $3.1 billion

So if it is not Feedburner, who will be next?
