As an adolescence growing up in the 60s many companies used subliminal advertising to attract adolescents to cigarettes' and alcohol.
Sexual innuendos were also big. The one I remember most was the Swedish girl in the Noxzema Commercial slowly saying "Take it off, Take it all off."
Today, Social Media Companies use algorithms and messaging to penetrate the brains of adolescents to become addicted to their web sites. Today's companies have far reaching (Billions) of customers and the outcomes are much more dangerous with the increase of suicides and addictions in our young people.It's just not adolescents adults are affected too but the companies involved today want the younger audience so they have many years to change their thoughts and cultural thinking. This is dangerous and it needs to be stooped by strict regulation world wide.
