Here's why:
* Ownership: The BBC is a publicly funded broadcaster owned by the British government. Channel 4 is a publicly owned but commercially funded broadcaster, meaning it generates its revenue through advertising and program sales.
* Funding: The BBC receives funding through a license fee paid by every household with a television. Channel 4 relies on advertising revenue and program sales.
* Programming: The BBC has a broad remit to provide public service broadcasting, including news, documentaries, drama, and entertainment. Channel 4 is more focused on alternative programming, often with a focus on youth audiences, independent films, and documentaries.
* Governance: The BBC is governed by a Board of Governors appointed by the government. Channel 4 is governed by a Board of Directors, with a majority of members appointed by the government.
While both are public broadcasters, they have different funding models, programming, and governance structures.
