Elizabeth Herbst-Brady, CEO of media buyer MagnaGlobal, is leaving to join MTV Networks, the Viacom unit confirmed.
Herbst-Brady will be executive vice president of ad sales strategy of MTV Networks' Music and Entertainment Groups, reporting to Jeff Lucas, who heads sales for the unit, which includes cable networks Spike, VH1 and TVLand.
She will oversee domestic ad sales strategy and business development, working closely with the EVPs in Lucas' group - Neil Holt, Sean Moran, Peter Griffin, Dario Spina, Mike Tedone, Brian Fays and Kevin Arrix, MTV Networks said.
The move comes just after most of cable's upfront deals have been negotiated. As head of Magna, Herbst-Brady headed negotiations for media agencies owned by Interpublic Group, including Universal McCann and Initiative. Lucas headed negotiations for most of Viacom's non-kids channels.
