I just visited guest blog who visit my blog in other day, then i interested about this article mention that:
"One of the big hurdles for the Linux community is money. Many times there are not the funds from any one group to actually get a platform popular enough for mainstream use. Google has invested
millions of dollars and will take a loss on much of the platform for a
number of years in order to get it popular. This money will be made back
through data that is provided by users as well as advertising. This is one of the only ways of getting Linux out there with a large company that has money.
