Research taken from Wikipedia: http://en.wikipedia.org/wiki/Popular_music
“Popular music belongs to any of a number of musical genres ‘having wide appeal’ and is typically distributed to large audiences through the music industry. It stands in contrast to both art music and traditional music, which are typically disseminated academically or orally to smaller, local audiences. The original application of the term is to music of the 1880s Tin Pan Alley period in the United States. Although popular music sometimes is known as ‘pop music,’ the two terms are not interchangeable. Popular music is a generic term for music of all ages that appeals to popular tastes, whereas pop music usually refers to a specific musical genre.”
Knowing this has helped me to understand the audience market for pop music video and who we can target our audience to.
