The SCO Group was a software company known for its Unix operating systems and related products. Founded in 1979, it gained prominence in the 1980s and 1990s as a provider of Unix solutions for businesses. The company became well-known for its legal battles over Linux, claiming that some of its code was used without permission. In the early 2000s, the SCO Group filed lawsuits against various companies and individuals, which led to significant controversy in the open-source community. Despite its efforts to assert its claims, the company faced financial difficulties and eventually filed for bankruptcy in 2007, marking a decline in its influence in the tech industry.
