Multiple reports this week have said that Google will get regulatory approval on its intended acquisition of Motorola Mobility as soon as next week.  If this happens as expected, the acquisition should close shortly thereafter.

This isn’t much of a surprise. When the deal was unveiled in mid August, 2011, Google had offered $40 per share. Motorola shares immediately spiked to over $38, reflecting small risk of the deal falling through. 

Stock TalkIn other words, nobody really believed Google would have trouble gaining regulatory approval. And why shouldn’t they get it? If Apple can own an entire platform and gain so much market share in the smartphone world, why shouldn’t Google be able to make its own hardware and aim to control the entire platform from software, to network infrastructure, to hardware?

Google says it wants Motorola’s patents, but also talks up the company’s hardware design capabilities. But I still think Google wants to own the entire platform so that it can solve the fragmentation problem before it gets out of control. 

There really aren’t any mobile OS vendors who don’t have significant stakes in hardware companies. RIM and Apple are the obvious examples, but so is Microsoft, with its quarterly $250 million dollar “platform support payments” to Nokia.

Android isn’t really open. That’s not a knock. It’s just the truth. The whole “open” argument does seem kinda brilliant though. Look how many vendors adopted it. Look how much market share Google now has in the mobile OS market. 

Do they really care about the long term success of the vendors? Maybe, but maybe not. Google cares about people using Google services and showing Google ads. They only need to support vendors until critical mass is achieved. As soon as the OS has critical mass among hardware vendors, app developers and consumers (check, check, and check) it has won. Google can then move onto fix problems such as fragmentation and integration into the larger consumer product ecosystem (home entertainment, etc).

The battle is changing, and Google is adapting along with the market. 

We’ve already seen that 8.5 percent of Internet use comes from mobile devices. That number is nearly double its year-ago level. Where do you think it will be in 2, 3 or 5 years? Probably a lot higher. Google is an advertising company. It’s critical that they position themselves such that user eyeballs are on services or content that Google controls. In my opinion, buying Motorola was a risk worth taking to protect Android’s growth and sustainability.
