Public service broadcasting refers to non-commercial TV and radio programs that are intended for public benefit rather than commercial purposes. It includes local news, arts, and religious programs. Public service broadcasters are state-owned but independent of political interference. In contrast, commercial broadcasters are privately owned and more focused on promoting advertisers' interests through entertainment and reality shows. Prasar Bharati is India's largest public broadcaster, comprising Doordarshan television and All India Radio. The BBC is the world's oldest and largest public service broadcaster, providing impartial broadcasting across television, radio, and online in the UK and worldwide.
