Area. And, sometimes things that look like failure, with persistence, become successes. Take Windows 1 and Windows 2 for instance. What if Microsoft had given up after version 2 did not succeed??

Maybe, Google could use some more marketing skills, but, with persistence, some of those "failures" you are talking about could become multi-billion franchises in the long run.

MS has also had a number of spectacular "failures" as you call them in recent years. The only things bringing in big money are the Windows and Office monopolies.

Finally, these are all very new frontiers, and the only way to learn is by trying and figuring out what does and does not work. Because Google does a lot of trying, they will also have more failures.
