PSBs provide quality and original content that can cater for niche or commercially unattractive market segments  PSBs create unique content which private broadcasters would be unable to produce as they strive for mass market appeal to satisfy the demands placed upon them by commercial interests looking to purchase advertising. PSBs create more educational and minority output which enriches society rather than just entertaining it.  PSBs can concentrate on creating high quality programming across all genres rather than simply producing mediocre populist programming such as low-cost game shows and reality TV. For example it is unlikely that commercial broadcasters would have aired nightly university lectures as the BBC did with its partnership with the Open University. PSBs are usually among the highest investors in the domestic content industries and nurture local creative talent.
