National defense is a classic example of a public good because it is non-excludable (people can't be excluded from its benefits) and non-rival (use by one person doesn't decrease availability for others). Pay-Per-View broadcasts are not a public good because they are excludable - only those who pay can access them. An apple and a seat in a bus are both private goods because they are both excludable and rival - if one person eats the apple, there is less for others, and if one person occupies a seat on the bus, there is one fewer seat available for someone else.
