Gregory takes up the role of development director for Telegraph Media Group and will oversee new ventures in broadcasting, mobile and online.
In September, the Telegraph announced a partnership with TV news service provider ITN to produce video content for telegraph.co.uk and other electronic media. However, this arrangement is expected to be expanded into linear TV programming. ITN produces news programmes for ITV and Channel 4.
It is understood that a new television channel, featuring Telegraph content, is likely to be broadcast online initially with a view to securing carriage on the Freeview and Sky digital platforms.
Since leaving Emap in March, Gregory has been working with his former Emap Radio boss, Tim Schoonmaker, for Macquarie Radio UK Holdings, a division of the Australian investment bank. They were respectively chief executive and chairman, but both are believed to have left the company.
The pair worked on a range of UK media deals including pitches for Plymouth's Diamond FM, Macquarie's first and only venture into British radio.
Of the company's three attempts to move into local radio, only its Plymouth bid was successful and, to date, the station has yet to launch, with speculation rife that Macquarie is looking to ditch the licence either before or after it is brought to air.
Schoonmaker is now said to be working for Credit Suisse, heading its European private equity arm, focusing on media.
Gregory, who helped make Magic 105.4 the number one radio station in London during his 11 years at Emap, will report to Dave King, executive director of The Telegraph Group, and chief executive, Murdoch MacLennan.
Insiders believe Gregory will be working closely with the commercial teams to accelerate the migration of traditional revenue to online solutions.
In recent weeks there has been speculation in the industry that Gregory was on his way to News Corporation, and he was also linked with a move to run the European expansion plans for MySpace.
