Is google earth a live telecast or satelitte image?

While google Earth imagery is not real-time (on average it is three years old), google is making some layers such as traffic and weather available near real-time updated on an hourly basis.

Also, there is a webcam layer integrated into google Earth that can show "live" scenes at selected locations -- which is mostly camera photos at fixed locations.

There are also third party data feeds such as real-time flight tracking available.
