During the 1960s, poor track maintenance and declining interest in the sport led to the end of horse racing at the facility. The last race horse was removed in 1971. In the same year, the college, which became
California State University, Northridge (CSUN) in 1972, built a football stadium on some of the acreage. Other parts of the property continued to be put to diverse uses. During the first half of the 1980s, Devonshire Downs was the venue for numerous
hardcore punk rock shows. Devonshire Downs is most widely known for hosting the three-day
Newport Pop Festival in June 1969, also known as Newport '69, featuring
Jethro Tull,
Jimi Hendrix,
Joe Cocker and nearly thirty other top acts. With over 200,000 people attending the festival over three days, it was, by far, the largest music event in the United States up to that time. News reports at the time indicated that hundreds were injured in a melee during the festival, and 200 police officers were deployed to restore order. ==1970s==
