Google earth has business layer

Today (or yesterday) Google added a business layer to Google Earth

"Today, we added a "Businesses" layer to Google Earth on iPhone, as well as to the "Geographic Web" folder in the desktop Google Earth version. To make them easily discoverable, you'll see them by default when you start the application next time. You'll find businesses like restaurants, bars, banks, gas stations, and grocery stores all just a touch away"

This is pretty interesting as you will now be able to find the closest shop of that which you need. You can also find the closest businesses and well whatever people add.
