There are no easy solutions for publishers seeking to boost their revenues in adverse conditions (which may be exacerbated by Brexit and possible caution around ad spend).
There are well known challenges for the print model, to advertising on-line (when the competition involves global technology companies with deep pockets and ad blocking is on the rise) and to making the subscription model work while driving to extend on-line readership (amongst many other issues).
Given these increasing challenges that surround publishers, the route through appears to lie in diversification of revenue streams (which exploit technology and data in new and savvy ways that remain complaint with complex legal regulations) that are not yet as vulnerable to the pressures outlined above.
Publishers are transitioning (and collaborating with third parties) to develop multi-media capability and we are likely to witness new and exciting ventures resulting which enrich customer interactions with publishing brands.
With print advertising collapsing faster than expected and digital advertising getting hoovered up by a few intermediaries, it's more important than ever that publishers find ways to profit from their products.
