Newsweek has marked the first year of its dedicated Europe edition with the launch a refreshed print and online editions, and new mobile and tablet apps – as well as a pledge to become digitally-oriented.

The US publisher held a briefing at its Canary Wharf offices in London this morning to announce that it was investing in an expanded editorial team, with new ‘Business’ and ‘Weekend’ sections to broaden its coverage.

A collection of celebrity ambassadors such as writer Margaret Atwood and philosopher Alain de Botton have also been recruited to “champion” its extended focus on investigative journalism.

The Newsweek Europe iPhone and iPad app rolls out in four weeks, with an Android version due “a couple of months after that”.

Since launching in March 2014, Newsweek Europe has grown a weekly print circulation of 70,000 across 40 markets, as well as an online audience of 1.2 million unique monthly users.

The publication is very much centred on a business traveller audience, with 92% of readers considered “top management”. Recruiting female readers has been a challenge; 84% of its readers are male.

While editor-in-chief Richard Addis said he sees a continued role for print as a “luxury add-on” and “shop window”, he acknowledged that, long-term, the “future [of Newsweek] is most definitely online”.

Print revenues are currently propping up its nascent digital and mobile presence, though owner IBT Media is confident Newsweek can match International Business Times’ global audience 50 million unique monthly users, providing scope for a health display and native ad proposition for advertisers.

Addis said that, if starting with a clean slate, he would start with three “equal” content teams developing text, audio and video content, and hopes to be able to invest in video content soon.

However, he warned against the dangers of handing over too much controls to social media platforms: “I can see a future where Facebook becomes the publisher, and we all just become content providers for Facebook, which is quite scary.”

Newsweek was relaunched globally as a print title in 2014 by IBT Media, after previously ending 80 years of publishing in December 2012.
