ShareTV and Wikipedia offer online lists of all TV series ever created. For inclusion in either list, the series must have aired at least one episode to a television audience.
Wikipedia categorizes its list of TV series by country. It includes lists of all TV series for 37 different countries. It lists the shows in alphabetical order by name, and the list includes the years the series actively aired and the genre of the series. Users can then click to view each TV series and read more information, such as its airtime length, its run time, plot and more. However, anyone can edit Wikipedia articles, and it isn't a fully credible source.
ShareTV lists all TV series alphabetically regardless of country and contains 100 entries per page.
