The apparent advantages of this model is that services related to public interest could be sustained. In terms of profitability, public interest programs, for example, over-the-air television, may not be as attractive as commercial ones in the provider perspective, but they are nevertheless beneficial for the society. Therefore, these services are  often implicitly enforced by the regulator through the license agreements.
This model offers advantages for public interest services because they can continue to operate despite potential financial challenges. While over-the-air television, for example, may not be as profitable as commercial offerings from a provider's standpoint, it still serves society and is often enforced by regulators through license agreements.
