It evolved from the midweek edition of the paid-for weekly newspaper the Watford Observer, which was renamed the Midweek Watford Observer in 1980. In 1984 it was renamed, descriptively if rather wordily, The Free West Herts & Watford Observer, then the Watford Free Observer in 1989. It’s borne its present title since 2004.
It comes out on Thursdays. A free e-edition is also available via the website.
