A poet and dramatist as well, Addison was the most popular of early eighteenth-century periodical essayist. He collaborated with Richard Steele on the Tatler (12 April 1709 to 2 January 1711), the Guardian (12 March to 1 October 1713), and especially the Spectator (1 March 1711 to 6 December 1712; second series, 18 June to 20 December 1714). He also conducted the Free-holder (23 December 1715 to 29 June 1716), the Whig Examiner (14 September to 12 October), and The Old Whig, which survived for only two numbers (19 March and 2 April 1719). None of these attained the success of the Spectator. Addison's only successful drama was the tragedy Cato (1713).
