Angry Birds maker Rovio plans to increase the proportion of revenue that it generates from non-gaming products to more than 50 percent, reports AllThingsDigital.

Speaking at the Open Mobile Summit, Rovio's chief marketing officer Peter Vesterbacka said that “more than half our business will be physical” in a few years’ time. Revenue from game-related physical merchandise currently stands at around 30 percent.

Rovio has extended its Angry Birds brand to include t-shirts, soft toys, board games and cookbooks, as well as activity parks in China. New products could include food, drink and other everyday products.

The company has also broadened its mobile games portfolio with the addition of Space and Star Wars versions of Angry Birds and spin-off game Bad Piggies. The company also launched Amazing Alex in July, a modified version of Casey’s Contraptions, the IP for which was acquired in May.

Vesterbacka has said in the past that Rovio is aiming to have a billion fans interacting with its products in the next few years.
