The Public Broadcasting Service (PBS) is a non-profit American public broadcaster and television program distributor. Founded in 1969, PBS provides educational and cultural programming to over 330 member stations across the United States. Unlike commercial networks, PBS relies on funding from member stations, government grants, corporate sponsorships, and individual donations. This funding model allows PBS to prioritize programming that serves the public interest, offering a diverse range of content including children's shows like "Sesame Street," documentaries like "American Experience," news and public affairs programs like "PBS NewsHour," and arts and culture performances.
