Nearly one in two children tune into Phineas and Ferb on Disney Channel and Disney XD, the firm has revealed. And the success of the TV show is also being mirrored across Disney's other divisions.
As a fourth season is confirmed - with new episodes due to roll out in 2014 - Disney has also said that Phineas and Ferb is the number one TV show for kids in its timeslot across all channels in the UK.
The feature length movie - Phineas and Ferb: Across the 2nd Dimension - is the third highest rating Disney Channel original movie of all time in the UK, while retail sales are up ten times year on year in 2011.
Apparel and home products in particular enjoyed strong success in the UK. A girls' fashion and home product range is set to launch later this year.
The brand is also popular online, with a dedicated mini site featuring premium content such as wallpapers, games and screensavers. iPad and iPhone applications for Phineas and Ferb has also recently launched, while the Nintendo DS Phineas and Ferb: Across the 2nd Dimension game hit the number two spot in the charts when it was released last year.
New level and costume packs are also available to download for action adventure video game, Disney Universe.
"Creating and nurturing successful franchises is key for us at Disney and throughout 2011 Phineas and Ferb has proved that it has the ability to span our different businesses, create value, whilst being truly multi-regional with its storylines, themes and characters," said Tricia Wilber, CMO, The Walt Disney Company EMEA and general manager, Disney Channels EMEA.
"Its success has demonstrated the continued resonance of great Disney storytelling with kids today and the pivotal role that TV plays in creating a leading franchise."
