In this episode of the Dog 'n' Bone, we sit down with two big dogs from business media publishing. Greg Grimmer, famed ad-man and CEO of Mediatel, is joined by Philip Swinden, MD of Haymarket Business Media.

The pair explore the future for printed trade magazines such as Campaign, discuss the upcoming launch of Haymarket's newest title - and Greg sheds light on his awkward showdown with Magnus Magnusson on the set of Mastermind.
