In their submission to the ABC and SBS Review, currently in progress, Stuart Cunningham and Terry Flew argue that how national public broadcasters respond to changes in the media environment arising from digitisation, convergence and changing societal needs and expectations can be best understood as a question of social innovation. In the 21st century digital media environment, where all media outlets are multi-platform and digitised in their modes of content production and delivery, it is better to understand the ABC and SBS as public service media organizations, rather than public service broadcasters. This emphasises how it is the services provided, rather than the delivery platforms, that are at the core of rationales for public support of the ABC and SBS.
