Answer:
The correct answer is A) fostered a sense of national cultural conformity.
Step-by-step explanation:
While Television had been around for a couple of years prior to World War II, it was only by the end of the war and during the economic boom that it's cultural impact was felt on a national level.
Just like what the radio did several decades ago, TV was able to do on a much larger scale and have a more meaningful visual impact.
Americans all over the country were able to watch the same sports, news, weather reports and even family friend entertainment programs.
This was able to build a strong cultural and national identity among various different regions of the country.
