Interesting idea by Dana Blankenhorn – how about Apple buying Sony? Would make an interesting inroad into portable cellphones/MP3 players, and also get them access to a lot of digital music for iTunes. I wonder to what extent there would be institutional obstacles, though. Sony is an old Japanese company and the shares may not be as licquid as a listing on NYSE should indicate.

The Japanese government would be in a lot of trouble if it failed to allow the acquisition of a Japanese company by an American company, after that company itself was built buying American companies (like Columbia Pictures).
Besides, Sony isn’t a keiretsu, like Mitsubishi. It is, as I indicated, an entrepreneurial company concentrated in a narrow range of industries.
Thanks for writing about it.
