In 1995 JJ Allaire co-founded Allaire Corporation creating the web development tool ColdFusion. In March 2001, Allaire Corporation was sold to Macromedia where ColdFusion was integrated into the Macromedia MX product line. Macromedia was subsequently acquired by Adobe Systems, which continues to develop and market ColdFusion. Starting in 2009, Allaire has been developing an IDE for the widely used R technical computing environment. An initial version of RStudio was publicly released on February 28, 2011. Later versions added an R debugger, R presentations, RMarkdown, and the Shiny R web application server.
