I think it’s impossible to answer the question in the OP without it being made more specific. What time period is this referring to when the question is asked? Today, or ten years ago, or twenty years ago or whatever? Where are the people who are asked this question? In the U.S. or in another country or in a specific part of the U.S. or another country? How old are the people that are asked this question? A specific age group or all adults or all people of any age? Are there any other limits on the people asked this question, like their interests or their income or their social status or any other way of dividing people into groups?
Furthermore, assuming we don’t just guess at the answer or poll some insignificant number of them, how can we get an accurate answer? There’s a polling system call YouGov that is reasonably accurate for the present in the U.S. They also do polls in nine other countries. If the question is about everywhere in the world, how would we (for instance) know the answer in North Korea accurately? (And I have no idea whether North Koreans know anything about music or television outside their country.)
