Grabiner, also a former Express Newspapers director and chief executive of ONdigital, which later became ITV Digital, joined venture capital company Apax Partners in 1999 to head up its media investment team.
When ITV Digital collapsed, Grabiner was linked to a potential rescue bid for the broadcaster. He is also said to be mulling a bid for the merged ITV.
It is not yet clear whether the Telegraph Group will be put up for sale. Its future within its parent company was plunged into doubt over the weekend, when it emerged that Hollinger had been making unauthorised payments to directors, including chairman Lord Conrad Black.
Lord Black announced his retirement yesterday along with the resignations of several other board members following revelations that $32.15m (£19m) in unauthorised payments had been made to executives, including $7.2m to Lord Black.
Hollinger has appointed investment bank Lazard to consider the options for the publisher, which owns the Chicago Sun-Times and the Jerusalem Post, along with the Telegraph Group, publisher of the Daily and Sunday Telegraph and The Spectator.
It is not yet clear whether Hollinger will be broken up or sold as a whole to an investor. The Daily Telegraph was optimistic that one option would be a substantial minority investor recapitalising the company.
Only last summer Lord Black vowed that the Daily Telegraph would never be sold, no matter how bad Hollinger's financial problems. However, that was before the unauthorised payments were exposed.
If the Telegraph Group is sold on its own, any rival publisher wanting to take control would likely face a competition inquiry, putting a bid by Apax in a strong position.
Overseas, the bidding is being led by the US financier Nelson Peltz, which, according to the Financial Times, has already begun due diligence.
