Speaking at Toronto Mobile Media World event, heard Toronto based Polar Mobile CEO Kunal Gupta speak. One of his examples was a long-term fave of mine among print publications, The Hockey News. Mr Gupta said that after they launched the mobile version of THN, they achieved 300,000 subscribers on mobile who did not cannibalize print sales or web sales. And where almos all print titles globally see a decline in circulation numbers, THN has achieved modest growth in circulation after the launch of the mobile version. One more tidbit - Polar Mobile have released four versions of the service since its launch. You have to adapt a lot and listen to your audience if you intend to remain successful in mobile..
