Bloomberg News reports that Rupert Murdoch’s effort to cash in on education is “riddled with failures.”

The education division at Murdoch’s News Corporation is called Amplify; its CEO is Joel Klein. Its biggest contract is in Greensboro, North Carolina. Amplify recalled its first batch of 15,000 tablets in 2013 when chargers melted and screens cracked.

“By the end of June, Murdoch’s News Corp. will have invested more than $1 billion in Amplify, its division that makes the tablets, sells an online curriculum and offers testing services. Amplify, which never set a timetable for turning a profit, has yet to do so. It reported a $193 million loss last year, and its annual revenue represented only about 1 percent of News Corp.’s sales of $8.6 billion.”

“The education effort has been riddled with technology failures, fragile equipment, a disconnect between tablet marketers and content developers, and an underestimation of how difficult it would be to win market share from entrenched rivals such as Houghton Mifflin Harcourt Co. in the kindergarten to high school education market.

“After all of these years of investment, it would really behoove them to show some wins,” said Tim Nollen, an analyst at Macquarie Capital USA in New York who has a “neutral” rating on News Corp. shares. “So far, I haven’t seen any……..”

“Amplify’s experience shows how even the most deep-pocketed new players find it challenging to change the way children are taught. Billionaires such as Microsoft Corp. founder Bill Gates and real estate and insurance investor Eli Broad have expressed frustration their philanthropy hasn’t done more to improve student achievement. Murdoch is discovering his own challenges as he seeks to make a profit from overhauling education — as have other education entrepreneurs before him.”
