History of DotNetNuke

The DotNetNuke application originally evolved out of another project, the IBuySpy Workshop. The IBuySpy Workshop application had been created by Shaun Walker as an enhancement to the IBuySpy Portal that started as a sample application for the .NET Framework. Early versions of DotNetNuke were released by Walker's company, Perpetual Motion Inc, while later development was expanded by the open source community.

The name DotNetNuke was coined by Walker by combining the term .NET with the word "nuke", which had been popular with pre-existing frameworks such as PHP-Nuke and PostNuke. The term DotNetNuke and DNN are registered trademarks in the US and Canada.

In September 2006, four members of the project's board of directors formed a corporation to oversee the development of the project. The new DotNetNuke Corporation was co-founded by Walker, Joe Brinkman, Nik Kalyani, and Scott Willhite and replaced Perpetual Motion Interactive Systems Inc. as the corporate entity behind the project.

On November 25, 2008, DotNetNuke announced Series A financing from Sierra Ventures and August Capital, and in February 2009, after hiring Navin Nagiah as CEO, a Professional Edition version of DotNetNuke has been released for business and enterprise customers. In February 2010 DotNetNuke announced a Series B financing from Sierra Ventures, August Capital, and Pelion Venture Partners.

In August 2009 a partner program was launched by DotNetNuke Corporation, aimed at providing support to the web design and development companies that build web sites using DotNetNuke. DotNetNuke Corporation also announced the acquisition of Snowcovered, an online market for DotNetNuke modules, skins, services and related products.

In October 2009, the 2009 Open Source CMS Market Share Report concluded that DotNetNuke was the leading .NET-based open source web content management system.

In 2013, the company was renamed to DNN Corporation.
