Making an update on Ping.fm pushes the update to a number of different social websites at once. This allows individuals using multiple social networks to update their status only once, without having to update it in all their social mediums individually. Ping.fm groups services into three categories – status updates, blogs, and micro-blogs – and updates can be sent to each group separately.

History

Ping.fm was created with the intent of making it as easy as possible to post updates to multiple social networking sites simultaneously. The idea came about when creators were updating status messages with micro-blogging sites Twitter and Tumblr. The idea of posting the exact same information in two places seemed a bit tedious, so Ping.fm was born.

Open Beta

After 6 months of being in closed beta, an announcement was made on Sep 2, 2008 that would no longer require private invite beta codes to be used to register and use the service. The launch into Open Beta was covered by outlets like Wired, and Mashable.

Mark Zuckerberg founded Facebook while he was a student at Harvard University. Website membership was initially limited to Harvard students, but was expanded to other colleges in the Ivy League. It later expanded further to include any university student, then high school students, and, finally, to anyone aged 13 and over. The website currently has more than 120 million active users worldwide.

Facebook has met with some controversy over the past few years. It has been blocked intermittently in several countries including Syria and Iran. It has also been banned at many places of work to increase productivity. Privacy has also been an issue, and it has been compromised several times. It is also facing several lawsuits from a number of Zuckerberg’s former classmates, who claim that Facebook had stolen their source code and other intellectual property.

Mark Zuckerberg founded “The Facebook”, originally located at thefacebook.com, on February 4, 2004 while attending Harvard University as a sophomore. The company dropped The from its name after purchasing the domain name facebook.com in 2005 for $200,000.

Membership was initially restricted to students of Harvard College, and within the first month, more than half the undergraduate population at Harvard were registered on the service. Eduardo Saverin (business aspects), Dustin Moskovitz (programmer), Andrew McCollum (graphic artist), and Chris Hughes soon joined Zuckerberg to help promote the website. In March 2004, Facebook expanded to Stanford, Columbia, and Yale. This expansion continued when it opened to all Ivy League schools and gradually most universities in Canada and the United States. In June 2004, Facebook moved its base of operations to Palo Alto, California. In October 2008, Facebook announced that it was to set up its international headquarters in Dublin, Ireland.

Facebook launched a high school version in September 2005, which Zuckerberg called the next logical step. At that time, high school networks required an invitation to join. Facebook later expanded membership eligibility to employees of several companies including Apple Inc. and Microsoft. Facebook was then opened to everyone of ages 13 and older with a valid e-mail address on September 26, 2006.

BusinessWeek has confirmed that Facebook, beginning in Autumn 2008, will allow its employees to sell stock at no more than a $3.75 billion valuation.

Updates are displayed on the user’s profile page and delivered to other users who have signed up to receive them. The sender can restrict delivery to those in his circle of friends (delivery to everyone being the default). Users can receive updates via the Twitter website, SMS, RSS, or email, or through an application such as Tweetie, TwitterFon, Twitterrific, Feedalizr, and Facebook. Four gateway numbers are currently available for SMS: short codes for the United States, Canada, and India, and a United Kingdom-based number for international use. Several third parties offer posting and receiving updates via email. Twitter had by one measure over 3 million accounts and, by another, well over 5 million visitors in September 2008, a fivefold increase in a month.

Twitter, founded by Jack Dorsey, Biz Stone, and Evan Williams, began as a research and development project inside San Francisco podcasting company Odeo in March 2006.

Odeo was co-founded by blogger (evhead.com) Evan Williams. In October, 2006 the company was bought out by management, and Williams, Stone, and other Odeo employees started another company named Obvious Corp. to operate Odeo and Twitter, another startup Williams had been testing in the offices for about a year. Twitter had been initially used internally by Odeo’s employees and became a product of Obvious at this time.

The service rapidly gained popularity: In March 2007, it won the 2007 South by Southwest Web Award in the blog category.[6] Dorsey, the man behind the concept of Twitter, gave the following playful acceptance speech at SXSW: “We’d like to thank you in 140 characters or less. And we just did!”

In April 2007, Obvious spun off the service as a separate entity under the name Twitter, Inc., with Dorsey as CEO until 2008 when Williams replaced him.

“Summize” was an internet startup using the Twitter XMPP stream to allow users to search twitter conversations in near real-time. On 15 July 2008, Twitter acquired Summize and rolled it into their own site at the subdomain search.twitter.com. At the time of the sale, Summize had 6 employees, of which 5 went on to work at Twitter. CEO Jay Verdy moved on to a new project.
