Lots of news today from Google, they also are now allowing people to download the Google Earth program for free. Inside Google pretty much broke the news first (even though many other sites were under embargo). In addition, Inside Google has the most detailed write up in terms of screen captures and walk throughs. The Search Engine Watch article was written by Chris Sherman and is named Google Earth Flies Free, which then Danny Sullivan blogged on this morning.
You can download Google earth here.
