New York Post: Viacom Media Networks sales boss Jeff Lucas has been so dogged by rumors that he’s splitting for Snapchat that he called a meeting just to tell staff it isn’t true.

Katelyn Kroneman, VP of linear and digital ad sales, is the latest to vanish from Viacom and appear at the disappearing-message service.
