Horowitz earned a Bachelor's degree from Columbia University in 1959 and a Master's degree from the University of California at Berkeley in 1961. In 1988, Horowitz created the Center for the Study of Popular Culture, now name the David Horowitz Freedom Center. The Center boasts 20,000-plus members and publishes four magazines, including Frontpagemag.com and Heterodoxy, a monthly focusing on "political correctness and other follies." Regarding the Center, the Southern Poverty Law Center writes, "Since its beginning, though, the Freedom Center has become the premier financier of anti-Muslim voices and radical ideologies, as well as acting as an exporter of misinformation that seeks to increase popular appeal for Horowitz’s fears and phobias."
