The closest thing I can come up with is that the're modeling after companies like this: http://www.textron.com/ http://www.textron.com/ Textron owns Bell Helicoptor, and EZ:GO Golf Cart company, among ~12 others, but the stock is all Textron stock. I guess its kind of like internal diversification. I realize Google is a decently unique company, so I'm not sure exactly why they did what they did, but the model they jumped to seems common enough.
