Perhaps this spooked the market:
"The fall in high margin advertising revenues will result in a 2017 profit reduction which is expected to reverse in 2018 as the strategy to address the industry trend by monetising content and expertise materialises"
As a holder, that is what I was hoping for too. Sadly the SP is currently down around 20p. Personally I didn't think the results were that bad. At least the dividend has been maintained - for now.
