Titan Publishing's Wallace & Gromit digital comic for Apple's iPhone has notched up over half a million downloads of the first free app.
Since its launch on November 7, the Wallace & Gromit digital comic has reached number one in the UK free books app store, a first for a British comic, and has also risen to the number three spot overall in the free apps chart.
All four paid for Wallace & Gromit comic apps have been in the top 20 paid apps in the UK book chart since their launch in November.
In addition, it is currently the number one free book download in America and Canada and number two in Australia.
Wallace & Gromit digital comics editor, Ned Hartley, said: "We've been amazed at how well our first app has done - Wallace & Gromit is such a great brand, and iPhone users obviously love them as much as we do."
The first Wallace & Gromit Comic, The W Files, can be downloaded for free at www.titanpublishing/digital. There are four other Wallace & Gromit comics available at the app store, for 59p/$0.99 each.
Wallace & Gromit digital comics are also now available for download on PSP.
