History

NonVisual Desktop Access (NVDA) was initiated by Michael Curran in April 2006 as a response to the high cost of commercial screen readers. Starting with a Python-based screen reader using Microsoft SAPI, the project provided support for Microsoft Windows 2000 onwards. In late 2006, it was officially named NVDA, and in 2007, NV Access was founded by Curran and James Teh to oversee continued development. Over the years, NVDA underwent significant advancements, including touchscreen support in 2012, support for Microsoft PowerPoint in 2013, and compatibility with Windows 10 in 2015. Its global popularity soared, becoming the second-most popular screen reader globally in a 2021 survey by WebAIM. NVDA's commitment to regular updates, community engagement, and technological enhancements has made it a widely used and respected tool for individuals with visual impairments, particularly notable for its accessibility, cost-free nature and inclusivity.
