This is a
list of the longest-running United States television series, ordered by number of years the show has been aired. This list includes only
first-run series originating in North America and available throughout the U.S. via national
broadcast networks, U.S.
cable networks, or
syndication. Series continuations (with name changes and/or changes in network) are noted, but series' revivals are treated as separate from the originals (see
The People's Court and
Jeopardy!). Series broadcast within the US but produced in other countries, such as
Coronation Street (50+ years) and
Doctor Who are not included.
