#8 “I’m feeling lucky”

Google's first official tweet was the words "I'm feeling lucky" in binary.

The "I'm Feeling Lucky" button, which bypasses the results page to take users directly to the first result of their search, has been estimated to cost Google around $100m in lost ad revenue every year.

#7 Gmail

Gmail released on December 16, 2005, and is now available in more than 50 languages. The idea for Gmail was pitched by Rajen Sheth during an interview with Google, and went on to be developed by Paul Buchhe. Initially the email client was available for use only by Google employees internally. Google announced Gmail to the public on April 1, 2004 by making fun of paper-based archiving by introducing "Gmail Paper", where a user could click a button and Gmail would purportedly mail an ad-supported paper copy email archive for free.
