What is the difference between pbs and commercial tv?

PBS (Public Broadcasting Service) is a non-profit television network in the United States that primarily relies on funding from government grants, donations, and viewer contributions, focusing on educational and cultural programming. In contrast, commercial TV networks generate revenue through advertising and sponsorships, often prioritizing entertainment and popular programming to attract larger audiences. This difference in funding sources influences their content, with PBS emphasizing educational value and public service, while commercial TV tends to focus on profitability and broad appeal.
