Google Video replaced Product Search in Google's main navigation, now that Google's comparison shopping site started to become popular.
Google Video first replaced Froogle on the homepage in 2006, two months before Google acquired YouTube.
A year later, Froogle replaced Google Video on the homepage and it was rebranded as Google Product Search.
And now Google Video is back on Google's main navigation, while Froogle is available in the "more" drop-down.
