What is the impact on society of changing sound reproduction eg from cassettes to CDs to MP3s etc?

The invention of cassette tapes had a huge impact on society and on the music industry in general. It was a more compact way of storing and listening to music, and it also increased the locations that were available for music to be heard and accessed. With the creation of cassette tapes, people were able to listen to music in cars and other previously less accessible locations, which made music more portable.
