Public service broadcasters receive funding from TV license fees paid by the public as well as government funds. Commercial broadcasters earn profits primarily from television advertisements. Subscription channels generate income from monthly or annual subscription fees paid by viewers to access additional channels. In the UK, the BBC and Channel 4 are examples of public service broadcasters, while ITV and Channel 5 are commercial broadcasters. Public service broadcasters rely on license fees, commercial broadcasters use advertising revenues, and subscription channels employ a subscription-based model of generating funds from viewers.
