Welcome to Open Study ^_^
The main way in which the advent of MTV, and the challenging of traditional values by movies and television impacted the generation of teenagers living during the 1980s is that it encouraged them to "rebel" agains the status quo of society--creating somewhat of a youthful counterculture that had no interest in tradition.
