Do Amazon and Google lock out competition?

Anti-monopoly cases have been known to reshape corporate America. In 1984 at&t’s telephone network was found to have excluded competing firms. The company was controversially broken up in a move that ultimately led to a boom in innovation among its rivals. Meanwhile, a case against Microsoft in 1998 may have kept the door open for Google’s subsequent rise. Microsoft had bundled together its Internet Explorer browser with its Windows operating system, and made other browsers more difficult to install. Some business historians think the case, by stopping this practice, made life easier for new browsers. It may also have distracted Microsoft from developing its own search engine.
