‘Harry Potter’ publisher sees magic in digital ink

London-based Bloomsbury Publishing moved into the digital era Tuesday, launching its first 24 digital downloads after a year in which boy wizard Harry Potter helped boost profits by 24 percent.

“Our first 24 titles went up an hour ago, and it’s a very exciting initiative, because although it’s not a big area now, it will be in the future,” Chairman Nigel Newton said. “We want to stake out our territory,” he added.
