Beat Generation
The Beat Generation was a literary movement started by a group of authors whose work explored and influenced American culture and politics in the post-war era. The bulk of their work was published and popularized throughout the 1950s. The central elements of Beat culture are the rejection of standard narrative values, making a spiritual quest, the exploration of American and Eastern religions, the rejection of materialism, explicit portrayals of the human condition, experimentation with psychedelic drugs, and sexual liberation and exploration.
Offbeat generation
The Offbeat generation was a loose association of like-minded writers working across different styles but united by their opposition to a mainstream publishing industry driven by marketing departments. The term—coined by Andrew Gallix in in February 2006—was a pun on the Beat Generation but more likely to be associated with the Chemical generation immediately before it (who were anthologised at the "Repetitive Beat Generation" also).
