In this Media Weekly, we talk challenger thinking – from reviewing Contagious’s Mavericks and Mischief Makers event (which celebrated left-field ideas and right-brain creativity) to reflecting on the key challenger strategies outlined in PHD’s leadership publication, Overthrow II.  Guests include PHD’s Clare Deacon, Strategy Director; George Henry, Digital Planner; Mandy Cross, Media Director; and Malcolm Devoy, EMEA CSO.
