Google Shopping, formerly Google Product Search, Google Products and Froogle, is a Google service invented by Craig Nevill-Manning which allows users to search for products on online shopping websites and compare prices between different vendors. Originally, the service listed prices submitted by merchants, and was monetized through AdWords advertising like other Google services. However, in May 2012, Google announced that the service (which was also immediately renamed Google Shopping) would shift in late-2012 to a paid model where merchants would have to pay the company in order to list their products on the service.
