MTV and the Walkman were big news in the '80s that spurred pop music and allowed artists to become stars overnight.
We can arrive at this answer because:
The '80s were a time of great cultural and artistic ebullition.
The arrival of MTV as a television channel focused on music was something that revolutionized the music market and the way artists were seen in the country.
MTV spurred the production of music videos, which allowed great artists such as Madonna, Michael Jackson, and others to become big stars overnight.
The Walkman, in turn, squelched tape sales that also created several pop stars.
That's because this instrument allowed people to listen to music anywhere, as long as they had the tapes of their favorite artists.
In this case, we can say that Walkman and MTV were great influencers in the 1980s.
