The software was called Tracktion many years before it was owned by a company with Tracktion in its name. When first released (2002), its sole author and designer Julian Storer sold it under the company name of Raw Material Software (this forum was once named after that company). Within a year or two, Mackie had taken over distribution and development, but left it for dead after version 3, which came out early in 2007. You can look back on this forum all the way to early 2004 and plenty of posts inbetween, many lamenting the demise of the DAW.
Until 2012 it was abandonware. In 2012, it was rescued from Mackie and resurrected by a new company called Tracktion Software Corporation, including its original author, and Tracktion 4 appeared early in 2013.
Part of the reason for the name change was the development of products not necessarily related to the DAW.
This gives an outline, but is a few years out of date: https://en.wikipedia.org/wiki/Tracktion
