Answer:
This shows society the cultural and ethnic diversity that exists in the country and that must be respected.
Step-by-step explanation:
When foreign language television stations are allowed in the country, this provides a great social impact, because it promotes the concept of cultural diversity and how it is accepted within a region and therefore must be respected, by all citizens. This impact is very strong in the USA since the country was literally created by foreigners and has a large Spanish, Chinese, European, Japanese community, among others.
In this case, foreign language stations not only reinforce the need for respect for different cultures and ethnicities, but also show foreigners that they are welcome and accepted within American culture.
