Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Dorsey introduced the idea of an individual using an SMS service to communicate with a small group. Work on the project started on March 21, 2006, when Dorsey published the first Twitter message at 9:50 PM Pacific Standard Time: "just setting up my twttr". The first Twitter prototype was used as an internal service for Odeo employees and the full version was introduced publicly on July 15, 2006.
The tipping point for Twitter's popularity was the 2007 South by Southwest festival. During the event, Twitter usage increased from 20,000 tweets per day to 60,000.[19] "The Twitter people cleverly placed two 60-inch plasma screens in the conference hallways, exclusively streaming Twitter messages," remarked Newsweek's Steven Levy. "Hundreds of conference-goers kept tabs on each other via constant twitters. Panelists and speakers mentioned the service, and the bloggers in attendance touted it."
The company experienced rapid growth. It had 400,000 tweets posted per quarter in 2007. This grew to 100 million tweets posted per quarter in 2008. In February 2010, Twitter users were sending 50 million tweets per day. Twitter moved up to the third-highest-ranking social networking site in January 2009 from its previous rank of twenty-second.
The company raised $200 million in new venture capital in December 2010, at a valuation of approximately $3.7 billion. In March 2011, 35,000 Twitter shares sold for $34.50 each on Sharespost, an implied valuation of $7.8 billion. In August, 2010 Twitter announced a "significant" investment lead by Digital Sky Technology that, at $800 million, was reported to be the largest venture round in history.

Google Search is the most-used search engine on the World Wide Web, receiving several hundred million queries each day through its various services.What distinguishes it from others? Of course, the answer is its logo. On certain occasions, it changes to a special version, known as a "Google Doodle".
The first Google Doodle was created in honor of the Burning Man Festival of 1998. The doodle was designed by Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. The attempt was very successful and since that Google had began to use various logos for special occasions. Clicking on a Google Doodle links to a string of Google search results about the topic, which can drive a lot of traffic to unsuspecting sites. Google doodles have been produced for the birthdays of several noted artists and scientists, including Andy Warhol, Albert Einstein, Leonardo da Vinci, Edvard Munch, Nikola Tesla, John Lennon, Michael Jackson, Freddie Mercury, Samuel Morse, Antonio Vivaldi, and Jules Verne among others.
Google even organized a Doodle4Google competition for students to create their own Google doodle. Winning doodles go onto the Doodle4Google website, where the public can vote for the winner, who wins a trip to the Googleplex and the hosting of the winning doodle for 24 hours on the Google website.
Since 1998, when first Doodle was hosted, more than 1000 of Doodles have been on Google search's start page.
