Wolfram Research is a private company that creates computational technology. Wolfram's flagship product is the technical computing program Wolfram Mathematica, first released on June 23, 1988. Wolfram Research founder Stephen Wolfram is the CEO. The company launched Wolfram Alpha, an answer engine on May 16, 2009. It brings a new approach to knowledge generation and acquisition that involves large amounts of curated computable data in addition to semantic indexing of text.[1] Wolfram Research acquired MathCore Engineering AB on March 30, 2011.[2][3] On July 21, 2011, Wolfram Research launched the Computable Document Format (CDF). CDF is an electronic document format[4] designed to allow easy authoring[5] of dynamically generated interactive content. In June 2014, Wolfram Research officially introduced the Wolfram Language as a new general multi-paradigm programming language.[6] It is the primary programming language used in Mathematica.[7] Other products include Wolfram SystemModeler, Wolfram Workbench,[8] gridMathematica, Wolfram Finance Platform,[9] webMathematica, the Wolfram Development Platform,[10] and the Wolfram Programming Lab.[11] Wolfram Research served as the mathematical consultant for the CBS television series Numb3rs, a show about the mathematical aspects of crime-solving.[12]
