Ebay will consider selling off its Skype internet phone subsidiary at the end of this year if it fails to find ways to use the fast-growing service to support its core e-commerce business, according to the company’s chief executive.

The comments from John Donahoe, who took over at the end of last month, are the most direct indication yet that Ebay is thinking of scrapping the ill-starred acquisition. It paid $3.1bn, but wrote down the value of the business by $1.4bn last year after concluding it would not match earlier hopes.
