What is the maximum percentage of the national audience that a TV station can reach under ownership limits?

The maximum percentage of the national audience that a TV station can reach under ownership limits is 39%. This regulation is part of the Federal Communications Commission (FCC) rules, which were established to promote competition and prevent media monopolies. By limiting how many viewers a single station can reach, these rules ensure a diversity of viewpoints and voices in the media landscape. This threshold allows large media companies to have a significant influence while also safeguarding against the concentration of media ownership that could stifle competition. Hence, the correct answer reflects the FCC's commitment to ensuring broadcast diversity and preventing excessive control by one entity in the national broadcasting arena.
