By 1968, hippie-influenced fashions were beginning to take off in the mainstream, especially for youths and younger adults of the populous "Baby Boomer" generation, many of whom may have aspired to emulate the hardcore movements now living in tribalistic communes, but had no overt connections to them. This was noticed not only in terms of clothes and also longer hair for men, but also in music, film, art, and literature, and not just in the US, but around the world.

             A sign of this was the visibility that the hippie subculture gained in various mainstream and underground media. Hippie exploitation films are 1960s exploitation films about the hippie counterculture. Examples include The Love-ins, Psych-Out, The Trip, and Wild in the Streets. Other more serious and more critically acclaimed films about the hippie counterculture also appeared such as Easy Riderand Alice's Restaurant 

            The Yippies, who were seen as an offshoot of the hippie movements parodying as a political party, came to national attention during their celebration of the 1968 spring equinox, when some 3,000 of them took over Grand Central Terminal in New York — eventually resulting in 61 arrests. The Yippies,  became notorious for their theatrics, such as trying to levitate the Pentagon at the October 1967 war protest, and such slogans as "Rise up and abandon the creeping meatball!" 

       In April 1969, the building of People's Park in Berkeley, California received international attention. The University of California, Berkeley had demolished all the buildings on a 2.8-acre (11,000 m2) parcel near campus, intending to use the land to build playing fields and a parking lot. After a long delay, during which the site became a dangerous eyesore, thousands of ordinary Berkeley citizens, merchants, students, and hippies took matters into their own hands, planting trees, shrubs, flowers and grass to convert the land into a park. A major confrontation ensued on May 15, 1969, when Governor Ronald Reagan ordered the park destroyed, which led to a two-week occupation of the city of Berkeley by the California National Guard. Flower power came into its own during this occupation as hippies engaged in acts of civil disobedience to plant flowers in empty lots all over Berkeley under the slogan "Let a Thousand Parks Bloom".
