Well it's quite difficult to know as each country preoccupations are different .... each sport events ( Superbowl, Stanley Cup etc .... ), each social events ( the actual student crisis in Quebec, Presidentials in US and France .... ) are more seen and LOTS more diffused in medias . I know it as I also run an online newspaper in Québec, each post can be shared over 4K on facebook, bloggers are payed an amount per 1000 cliks .... this one is only in french language, so really for local visitors, but even here, you got to stick on the local news to keep interests of the visitors . ..... so, in every sector, not even in adult business, noone's got the good answer
