"A very recent historical fact that is weirdly not talked about as much as it should be — Microsoft had accumulated such a big monopoly over the personal computer market through the 80s and 90s that in 1997 Microsoft was nearly broken apart by the US government.

In an attempt to avoid an investigation, Microsoft invested nearly $150 million into a then-failing Apple Computer to give the US government less ammunition in a potential anti-trust case. This saved Apple from bankruptcy and helped them to become one of the biggest tech companies in history. Microsoft, however, profited off of this investment. In 2003, Microsoft sold their shares in Apple for nearly $600 million."
