Microsoft was arguably the first, the case fell apart and ended up a settlement because the Judge presiding over the case violated the court code of conduct by discussing the case with the media. Something laughable in 2024.

That being said, the trial is the basis for the action taken against Google:

> However, the Circuit Court did not overturn Jackson's findings of fact, and held that traditional antitrust analysis was not equipped to consider software-related practices like browser tie-ins.

Another interesting outcome of the trail was that it established a playbook that others, namely Google, could follow to avoid antitrust litigation. I would argue that Google's ability to operate as a monopoly for so long was largely a result of the outcomes of the Microsoft trial.
