Last year, Hearst Magazines CEO David Carey said that he expected the company to hit 1 million digital subscribers for the company’s tablet editions. Hearst fell short of that goal by the end of 2012, but just hit the 1 million  mark this past March.That’s an impressive number that includes subscriptions across the three major tablet devices — iPad, Kindle and Nook.Carey said in a video interview with All Things D that the Nook, Kindle and iPad mini devices have been great for getting digital subscribers for the company’s womens’ titles, as their 7-inch screen makes them easier to carry in purses, etc. than the 10-inch iPad.Carey also said that 40% of website traffic is through mobile and tablet devices — and growing. For that reason, the company plans on growing its mobile and tablet presence and offerings, even though they’re not making as much money through digital formats than through print (of the company’s 300 titles, only 20 are sold in the US; 280 are sold in other countries, many of which enjoy a print industry that is not yet in decline).
