Google Reader was a news aggregation service that allowed users to access feeds from multiple websites in a single interface. It launched in 2005 and was shut down in 2013 because it no longer aligned with Google's strategy and had lost traction internally. Its closure led over 500,000 users to migrate to alternative services like Feedly on the same day. Experts believe Google Reader could have avoided shut down by incorporating its features into Google Plus, showing ads, or allowing paid subscriptions to premium content through partnerships with media websites.
