#4 Dodgeball

Dodgeball was a location-based social networking service that allowed users to communicate and broadcast their location to other users via text message. In January 2009 Google executive Vic Gundotra announced in Google Code Blog that the company would 'discontinue Dodgeball.com in the next couple of months, after which this service will no longer be available'. This service was replaced by Google Latitude.

#3 Google Wallet

Google Wallet was an innovative technology that clubbed online money transactions via credit cards with the user’s Smartphone. Here the Smartphone played the role of being a wallet. This was a really cool idea and was on the verge of trendsetting the future but unfortunately was implemented too soon for the masses to grasp, and the fear of its wrong implications led to people shunning it and the idea was soon dropped by Google.
