Pearson reveals mobile/tablet boosts for Financial Times and Penguin

15% of FT new subscriptions are mobile, while 14% of Penguin sales are e-books.

Publishing group Pearsons' latest financial results reveal strong digital growth at two of its divisions: newspaper the Financial Times and book publisher Penguin.

Mobile devices now take a 22% share of traffic to the FT.com website, and more than 15% of new subscribers to the paper's digital offering are on mobile devices. The company boosted its digital subscribers by 34% to nearly 230,000 in the second quarter of this year.

Meanwhile, 14% of Penguin's global revenues for the same quarter came from e-books, a rise for that category of nearly 130% year-on-year thanks to the popularity of devices like Amazon's Kindle and Apple's iPad.

"We have been growing in e-books and other digital programmes exponentially," said Pearson CEO Dame Marjorie Scardino. "People want to buy a whole book, they don't want to buy a chapter or two. Digital books are a better margin product for us."
