Final answer:
A football game on ESPN is a quasi-public good as it is sold on a per-household basis, while a game on NBC, CBS, or ABC is a public good as it is freely broadcasted to anyone with a television and antenna.
Step-by-step explanation:
A football game on ESPN is considered a quasi-public good because it is sold on a per-household basis. This means that individuals must pay for access to watch the game. While it is accessible to many people, it is only available to those who can afford to pay for it. On the other hand, a game on NBC, CBS, or ABC is considered a public good because it is broadcasted freely over the airwaves and can be accessed by anyone with a television and antenna. It is non-excludable, meaning that no one can be prevented from watching the game, and non-rivalrous, meaning that multiple people can watch the game without diminishing the experience for others.
