Woodstock was a famous music festival held in 1969 that brought together nearly half a million people to see iconic artists of the era like Jimi Hendrix, Janis Joplin, The Who, and Crosby, Stills, Nash & Young. It was organized as a profit-making venture by Michael Lang, John Roberts, Joel Rosenman, and Artie Kornfeld but ended up being free for attendees. While there were some logistical problems due to the massive crowds, Woodstock came to represent the counterculture movement of the 1960s and had a generally peaceful atmosphere. It was later memorialized through an acclaimed documentary and album of the event.
