Yelp was started out of MRL Ventures, an incubator Max Levchin and several former PayPal executives founded to develop Levchin's investment projects.^[8] In late 2004, Levchin brought up the topic of Yellow Pages, which had been worked on since the incubator was started, with Jeremy Stoppelman and Russel Simmons. The two brainstormed over lunch about Jeremy's difficulty using the internet to find a local doctor, then pitched Levchin shortly after on building a site where users could ask friends for recommendations for local services by email.^[8][9][10] That day Levchin agreed to invest $1 million in the project.^[8] MRL co-founder, David Galbraith, who had instigated the research into a Yellow Pages product, came up with the name "Yelp."^[11]
The initial site was hard to use, and attracted few readers or reviewers.^[10][12] In an "a-ha moment", Stoppelman and Simmons noticed that an increasing number of users were using a feature that allowed them to write reviews without being prompted.^[9][10] They relaunched the site in February 2005 based on unsolicited review writing.^[13]
Yelp's early review community was grown in part through Yelp parties, which were held at local businesses looking to attract patrons.^[14] The Yelp Elite, a category of super-users chosen by Yelp, was created in 2005 to reward the best reviewers.^[15] The Yelp Elite were invited to parties and other special events.^[12][16] The Yelp site had 12,000 reviewers in 2005, which grew to 100,000 in 2006.^[12] In early 2007, Yelp introduced "People Love us on Yelp" stickers to raise awareness for Yelp.^[17] By 2008, the website had fifteen million monthly visitors.^[18][19] Three years after Yelp was founded, it was active in 24 cities. Website traffic almost double over a six month period starting in late 2007 and the number of reviews passed two million.^[20]

Yelp, Inc. raised $5 million in venture funding from Bessemer Venture Partners in October 2005, which was used to expand to New York City, Chicago and Boston.^[12] Another $10 million was raised in October 2006 with Benchmark Capital,^[21] followed by $15 million with DAG Ventures in February 2008.^[22][23] In January 2010, Yelp raised $100 million in venture capital from Elevation Partners to fund an increase in sales staff.^[24

Andrew Bohuslavizki-Microsoft

Andrew Bohuslavizki-Microsoft Corporation is an American multinational software corporation headquartered in Redmond, Washington that develops, manufactures, licenses, and supports a wide range of products and services related to computing. The company was founded by Bill Gates and Paul Allen on April 4, 1975. Microsoft is the world's largest software maker measured by revenues.^[4] It is also one of the world's most valuable companies.^[5]
Microsoft was established to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows line of operating systems. The company's 1986 initial public offering, and subsequent rise in its share price, created an estimated three billionaires and 12,000 millionaires from Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions. In May 2011, Microsoft acquired Skype Technologies for $8.5 billion in its largest acquisition to date.^[6]
As of 2013, Microsoft is market dominant in both the PC operating system and office suite markets (the latter with Microsoft Office). The company also produces a wide range of other software for desktops and servers, and is active in areas including internet search (with Bing), the video game industry (with the Xbox and Xbox 360 consoles), the digital services market (through MSN), and mobile phones (via the Windows Phone OS). In June 2012, Microsoft announced that it would be entering the PC vendor market for the first time, with the launch of the Microsoft Surface tablet computer.
In the 1990s, critics began to contend that Microsoft used monopolistic business practices and anti-competitive strategies including refusal to deal and tying, put unreasonable restrictions in the use of its software, and used misrepresentative marketing tactics; both the U.S. Department of Justice and European Commission found the company in violation of antitrust laws.
