"John Ridding, the chief executive of The FT ... said improvements in collecting and mining customer data were a big reason digital sales accounted for 24 percent of The FT’s revenue last year, a big jump from 19 percent a year earlier and a considerably higher percentage than many other publishers can claim. ... Mr. Ridding said The FT was considering joining Google’s new One Pass subscription system, which will take a commission of 10 percent and share customer data with publishers. An iPad without The FT in its digital newsstand might be a losing proposition for both parties. Yet if Apple sticks to its position, Mr. Ridding said, “it would be a shame, not just for us, but for the broader ecosystem that has developed in recent years around these devices. It requires some thought before harm is done."
