The Twilight Zone S03E29

A normal, everyday guy discovers a camera in his closet. Puzzled, a repairman shows up to fix it, and secretly informs him that his life is being televised, and is a top-ratings grabber. The guy, John, doesn't want his life to be aired, and decides to quit. He soon finds that he misses the fame and popularity, albeit was kept secret from him. He has the repairman secretly reinstall the camera, begins to go back to his everyday "popular" televised life, and the ratings start pouring in again.
