Final answer:
Rock music of the 1960s and 1970s was largely publicized through radio and television, with notable contributions from technology such as the '45' record. Shows like The Ed Sullivan Show further propelled the genre into the mainstream, despite the resistance from the adult population.
Step-by-step explanation:
Rock music of the 1960s and 1970s was publicized through various means, marking a monumental shift in the cultural fabric of America. Radio played a pivotal role initially, allowing DJs like Alan Freed to popularize the genre, which embodied themes like young love and independence. Television, despite the initial resistance from adults, served as a powerful medium through which rock music reached a wider audience.
Shows like The Ed Sullivan Show and American Bandstand made it possible for teens to see their music idols and for artists from different racial backgrounds to gain exposure. Additionally, innovations in technology, such as the '45' record and solid-body electric guitars, helped in the recording and distribution of rock and roll music.
The period also saw record companies breaking racial barriers as economic demand for the new genre grew, thereby leading to a more integrated music culture.
