Microsoft was sued simply for bundling IE with Windows, which sounds crazy when you think about it. But at the time it seemed like selling browsers was going to be huge and Microsoft basically killed Netscape. With Windows, though, you were always free to install other browsers and set them as the default unlike iOS.

In the end the case kinda fizzled out as the times were changing so fast. Browsers kinda became an accepted "default" application to go along with an operating system.

I have to admit with all of the lawsuits in the software industry, I'm kinda surprised that Apple hasn't gotten more heat.
