#2 Google Health

Google health service allowed users to keep their health records in a centralized location - either manually or by logging into their accounts at partnered health services providers. The company wanted ‘to create a service that would give people access to their personal health and wellness information’. But the service was shut down in early 2013 and Google stated this on its official website: “Now, with a few years of experience, we’ve observed that Google Health is not having the broad impact that we hoped it would. There has been adoption among certain groups of users like tech-savvy patients and their caregivers, and more recently fitness and wellness enthusiasts”.

#1 Knol

Knols were authoritative articles about specific topics, written by people who know about those subjects. It was built to encourage experts to contribute their knowledge online and make it accessible to everyone. But many saw knol as Google’s attempt to compete with Wikipedia and it was soon phased out in favour of Annotum. All the content was deleted by October 2012.
