Trinity Mirror chief Sly Bailey has outlined the publishers plans for paid-for apps but says there are "no plans" for an online paywall across its titles.

Bailey revealed that the publisher will launch its first paid-for apps for tablet devices, including the iPad, in the "next few weeks".

She also said the company will start to offer advertisers marketing services such as web design, SEO, social media strategy and online PR.

Bailey said that readers "have zero interest" in a full paywall model for newspaper content but that the group was set to trial an online payment system for specialist news on some of the websites serving its regional newspapers in April.

She said: "We are trialing whether or not there is an appetite by consumers to pay for higher value content, starting with selected business coverage in the regionals."

Of the proposed digital marketing offering aimed at advertisers, Bailey revealed: "It is very much the future of local media. Clients are demanding it and we want to be able to develop expertise in those areas."

Trinity Mirror acquired Liverpool agency Rippleffect in April 2008 and Bailey revealed that a typical trade customer, after first buying advertising through newspaper or online channels would go on to spend £12,000 to £15,000 on a variety of digital services with the agency.

The publisher yesterday posted an operating profit rise of 17 per cent as it continues to consolidate in the regions.
