NEW YORK: Joe Becker, the VP and head of MWW Group's digital group DialogueMedia, is leaving the agency, he confirmed. However, agency CEO Michael Kempner said he plans to expand the practice with several new hires, including filling the leadership position for the practice. Most recently the firm added Sav Banerjee as senior digital strategist. Banerjee, previously a social media engineer for Gannett Digital, will now develop strategic social media campaigns for MWW clients. Becker declined to elaborate on his future plans at this time.
