History
Launch preparations began on May 15, 2009 at 7 pm CDT and were broadcast live on Justin.tv. The plan was to publicly launch the service a few hours later, with expected issues due to extreme load. The service was officially launched on May 18, 2009.
Wolfram Alpha has received mixed reviews. Wolfram Alpha advocates point to its potential, some even stating that how it determines results is more important than current usefulness.
On December 3, 2009, an iPhone app was introduced. Some users considered the initial $50 price of the iOS app unnecessarily high, since the same features could be freely accessed by using a web browser instead. They also complained about the simultaneous removal of the mobile formatting option for the site. Wolfram responded by lowering the price to $2, offering a refund to existing customers and re-instating the mobile site.
On October 6, 2010 an Android version of the app was released and it is now available for Kindle Fire and Nook. A further 71 apps are available which use the Wolfram Alpha engine for specialized tasks.

Famous quotes containing the word history:
“... in a history of spiritual rupture, a social compact built on fantasy and collective secrets, poetry becomes more necessary than ever: it keeps the underground aquifers flowing; it is the liquid voice that can wear through stone.”
—Adrienne Rich (b. 1929)
“Spain is an overflow of sombreness ... a strong and threatening tide of history meets you at the frontier.”
—Wyndham Lewis (1882–1957)
“The history of literature—take the net result of Tiraboshi, Warton, or Schlegel,—is a sum of a very few ideas, and of very few original tales,—all the rest being variation of these.”
—Ralph Waldo Emerson (1803–1882)
