This is not a new or unprecedented situation. Democracies have faced the
issue of monopolistic or oligopolistic media companies in the past, during the
heyday of broadcast television. The universal response by liberal democracies
was to regulate broadcast media, and many continue to do so to varying
degrees. This power to regulate media exists despite the commitment of all
modern liberal democracies to protect fundamental freedom of speech and is as
true in the United States as it is in Europe or Asia.

In order to understand the possibilities for state regulation of internet
platforms in the United States, it is therefore useful to look at the history of
regulation of legacy media.
