dentsu dissolves Vizeum under iProspect, new entity to roll out in phases Details 14 January 2021 Dentsu International has folded Vizeum under iProspect, with the new entity led by global president Amanda Morrissey (pictured below), bringing together more than 8,000 media and performance specialists across 93 key global markets. The new agency will be launched through a phased market plan over a three-month period and is targeted to complete by 31 March this year. While dentsu has yet to iron out the specifics for how the integration will impact its Asia Pacific operations, its spokesperson told MARKETING-INTERACTIVE that "the new iProspect media agency will access the broader dentsu capability set, allowing clients the flexibility to build bespoke and specialised teams with resources from across the network seamlessly".
