IBT has an interesting interview with Bas Seelen of Spilgames, explaining how the audience for casual games has expanded:
At first it was mainly women that played casual games online but now we have three brands to cater for a wide range audience because of the uptake from different demographics.
So we have come full circle, from catering to an audience that includes women, to catering to an audience that includes men.
It remains an open question how this will all play out with the new consoles. Has the time for consoles passed, or is there still a sufficiently large audience for them; an audience whose desires for games are not being fulfilled in mobile, browser-based or computer-based games?
