Commercial broadcasters have to directly interact with their audience to ensure that the programming being provided is what the public actually wants to consume. Commercial broadcasters have to pull in audiences whereas the (partly) publicly funded PSBs have a financial safety net which allows them to push content onto the audience in an elitist manner and allows them to essentially tell their audience what is good for them. It is also erroneous to suggest that minority tastes are not served by commercial broadcasters. Technology has allowed for a greater number of broadcast channels and as a result many of these specialize to cater for particular niches, for example, The History Channel.
