The powerful street view feature of google maps

I never knew about this particular facility which is being offered by google now a days. This is what is being called as "street view" and it allows you to see and have a look of the real street through google maps.

Now using the service on google maps, you can enjoy a real world interactive view of any street anywhere in the whole country of United States of America and you can locate and view any specific location through street view from the google maps interface itself! Overall this is a real great service that google is offering! I wonder how google will be making money from the service!
