Google has changed the "Products" link in the main Google navigation bar from "Products" to "Shopping" last night. Here is a picture:
You can see, just a couple days ago, the link said "Products." Around Thanksgiving time, Google replaced the Video links with Products, we guess in anticipation of the holidays. Maybe the word "Products" didn't give them the click through they were looking for. So now they are giving "Shopping" a try.
Clicking on the shopping link, still takes you to Google Product Search. Originally, Google Product Search was named Froogle but that was changed back on September 25 of last year. All these name changes: Froogle ---> Google Base ---> Google Product Search ---> Google Shopping, what is next?
It still seems Google has not changed the name of the search vertical. It just seems they changed the link in the navigation from Products to Shopping.
