Angry Birds Tale
Angry Birds involves catapulting cartoonish birds into fortresses built by egg-stealing green pigs but Vesterbacka (chief marketing officer of Angry Birds creator Rovio) said Rovio is "not a games company".
What we are building here is the next generation of entertainment franchises.
With some 300 million downloads, the addictive game is heading for global domination.
However, success doesn't come overnight.
"We built 51 games before Angry Birds so it wasn't like we were an overnight success." said Vesterbacka.
Rovio has successfully expanded the Angry Birds franchise from the virtual world to the real world despite being repeatedly advised that it would not work.
"We've been told time after time that we're not supposed to do movies, books, toys," he said. " We sold like 8 million toys."
It's not "rocket science". If you are a strong brand, if you have a strong following of fans you can do anything.
Could Rovio dethrone mobile phone maker Nokia as Finland's most important company?
