NeXT later released much of the NeXTSTEP system as a programming environment standard called OpenStep. NeXT withdrew from the hardware business in 1993 to concentrate on marketing OPENSTEP for Mach, its own OpenStep implementation, for several original equipment manufacturers (OEMs). NeXT also developed WebObjects, one of the first enterprise web application frameworks. WebObjects never became very popular because of its initial high price of $50,000, but it remains a prominent early example of a Web server based on dynamic page generation rather than on static content.
