Answer: Television
Needs are those goods and services that are required for an acceptable life. This includes adequate food, clothing, shelter and health care. Wants, on the other hand, are goods and services that are desirable, but that are not truly necessary. One might need shelter, but not a mansion in Beverly Hills.
Deciding what a want and a need is can be complicated, as it can depend on culture, and advertising often tries to turn our wants into needs.
