Answer:

Step-by-step explanation:
The main topic of the text is to show how the media was already very interested in classical music, since there were columns and articles on this artistic segment in all major newspapers, in addition to the fact that it was common for media outlets to have their own orchestra and specialized writers on that. However, that interest has been lost and today we do not see classical music being covered by press vehicles and not even being disseminated with the same frequency as before.
This can be seen in the first line of the text that states “It’s clear that the mainstream media have lost interest in classical music. "
