How did the cultural and tech shifts of the 1960s and 70s revolutionize advertising and consumer engagement?

In terms of regulations, the 1960s and 1970s brought about a heightened awareness of advertising ethics, leading to the establishment of stricter standards. Claims about products had to be substantiated, and concerns over misleading advertisements led to an increase in regulatory oversight. This shift not only aimed to protect consumers but also pushed brands to market responsibly, ensuring their messages aligned more closely with consumer truths.
