An other interesting part of the local newspaper market in this area is there can be an issue with a cover price that can be obtained in retail outlets, but a lesser newsworthy free issue of the same area paper (usually with a slightly different name) but with the same number of advertisements that is delivered to the home by local agents
I've always assumed the local papers can split their distribution between paid-for copies and the free ones delivered to people (although we no longer get any free paper delivered, and haven't for some years).
The Welwyn Hatfield Times is sold for 60p or whatever, but is available to pick up for free at the Galleria shopping centre, and possibly some other locations.
I guess that with dwindling sales, the publisher has taken the decision to give away copies free to keep the circulation up or else risk losing even more advertisers.
Ads are no doubt shared between other titles in the group, such as different regional editions of what's essentially the same paper (so many, but obviously not all, stories are shared).
I do wonder how long local papers will last. All have online editions, but the WH Times has an archaic content management system, which means articles look horrible - and the commenting system is terrible too. A shame as a good commenting system is clearly what drives traffic these days, so these sites are missing a trick to boost page views and uniques (as people come on to comment from shared stories - just like the Daily Mail makes a fortune from).
