It’s published by Newsquest (Southern) as part of its Avon Advertiser series; it first appeared as a separate edition in 1983. (The other two titles in the series are the Salisbury & Amesbury Avon Advertiser and the Ringwood, Verwood & Fordingbridge Avon Advertiser.) Unlike the other titles, though, it’s a companion to the Bournemouth-based Daily Echo and shares that newspaper’s website and editorial offices.
It’s published on Wednesdays. It has no website of its own; the link below is to the Echo‘s website, where a free e-edition can be found.
