Dennis Prager is a nationally syndicated radio host, author, and co-founder of PragerU, the digital education platform that became one of the most-viewed sources of political and cultural content on YouTube and social media.

Radio Career

Early Broadcasting (1982-1990s) Prager began his broadcast career in 1982 hosting Religion on the Line on KABC in Los Angeles, a Sunday night religious talk show that achieved top ratings. His success led to a weekday talk show, where he developed a format blending cultural commentary, philosophical discussion, and audience engagement.

The Dennis Prager Show (1999-Present) Prager launched his nationally syndicated weekday radio show, eventually distributed through Salem Radio Network. The program became one of the most listened-to talk radio shows in the United States, reaching millions of listeners across hundreds of stations. His radio approach emphasized long-form discussion of ideas, values, and cultural questions rather than exclusively political commentary.

PragerU and Digital Media

Founding PragerU (2009) Prager co-founded PragerU (Prager University) with Allen Estrin in 2009. The platform was built around a format of five-minute educational videos covering political, economic, historical, and cultural topics. Each video features a single presenter explaining a focused topic, drawing on academics, commentators, and public figures as hosts.

Digital Growth (2010s-Present) PragerU grew into a major digital media operation, accumulating over six billion total video views across platforms. The organization’s YouTube channel became one of the most-subscribed political content channels, and its videos gained wide distribution on Facebook, Instagram, and other social media platforms. PragerU’s success demonstrated how short-form, shareable educational content could achieve massive reach in digital political discourse.

Content Moderation Debates PragerU became a focal point in debates over platform content moderation after some of its videos were age-restricted or demonetized on YouTube. The organization pursued legal challenges against Google, arguing that YouTube’s content policies unfairly limited the reach of its videos. These disputes contributed to broader national discussions about how platforms moderate political content.

Writing and Public Intellectual Career

Author and Columnist Prager authored several books on religion, morality, and cultural topics, including The Nine Questions People Ask About Judaism (1975, co-authored with Joseph Telushkin), Happiness Is a Serious Problem (1998), and The Rational Bible commentary series. He also maintained a syndicated column covering political and cultural issues.

Public Speaking and Advocacy Prager spent decades as a public speaker and lecturer on topics related to religion, ethics, and American civic life. His early career included advocacy work on behalf of Soviet Jewry, serving as national spokesman for the Student Struggle for Soviet Jewry.
