David Lawrence Prager, born on January 17, 1977, in San Diego, California, is the eldest son of conservative radio host, author, and PragerU founder Dennis Prager from his first marriage. Maintaining a relatively low public profile compared to his father, David has built a career as a tech entrepreneur in media production, technology, and content creation. He began his professional journey with a White House internship during the Clinton Administration, gaining early exposure to political environments, and later worked early at Facebook. Prager graduated from the University of Wisconsin with degrees in Political Science and Journalism, and later attended Yeshiva University, reflecting a blend of secular and religious educational influences given his family's Jewish background.

In 2005, Prager co-founded Revision3, a pioneering San Francisco-based multi-channel network that produced and distributed streaming television shows on niche topics such as technology, gaming, comedy, politics, and DIY content. As Vice President of Special Projects, he contributed to acclaimed programs like Diggnation and Systm, establishing himself as a key figure in early internet video production. Revision3 operated as a subsidiary of Discovery Digital Networks from 2012 until its closure on March 31, 2017. His work in this space earned him credits as a producer, camera operator, and production manager in the industry. He has also founded other ventures in digital media.

Currently based in Hollywood, California, Prager is affiliated with PragerU, the conservative educational media organization founded by his father, where he leverages his media expertise. With over 500 professional connections on LinkedIn, he continues to operate within conservative-leaning media networks, though details of his specific role remain somewhat private. Prager's career trajectory highlights a transition from political internships to innovative digital media entrepreneurship, bridging technology and content creation.
