Earlier this year, the group, which publishes 220 titles across England and Wales, trialled new page-turning software, PageSuite, which allows readers to read digital versions of Tindle's print pages online.
The digital newspapers allow readers to click through these digital pages, which are separate from the free-to-access Tindle websites that do not carry exactly the same content as the newspapers.
Readers can subscribe to editions of the paid-for papers or buy a monthly, six-monthly or annual subscription using either a credit card or the payment system PayPal.
The initial trial involved three free and three-paid for titles and, following its success, Tindle Newspapers has increased its estimate of the revenue generated by selling its news content online.
Brian Doel, group managing director, said the publisher originally expected only a handful of paid online subscriptions in its core circulation areas, with most coming from foreign parts, However, many subscriptions, worth thousands of pounds, came from local subscribers.
Doel said some people "obviously prefer to read their local papers on their computers" and as many Tindle papers had already survived technology changes for 150 years or more, this online move would "help guarantee their survival for another 150".
Last week, regional publisher Johnston Press began a three-month trial of paywalls across six of its weekly titles, including the Whitby Gazette, Northumberland Gazette, Worksop Guardian, Ripley and Heanor News and two Scottish titles, The Southern Reporter and Carrick Gazette.
