The brunt of the Viacom layoffs hit Nickelodeon yesterday and today, sources tell Deadline. I hear a number of executives and assistants were affected in such areas as preschool, animation, legal and talent. I hear among those who have departed in the restructuring are Emmy winner Teri Weiss, Nickelodeon’s EVP Preschool Programming; Kay Wilson Stallings, SVP, Production & Development, Nickelodeon Preschool, Nick Jr., Nick Jr. and NickMom; and Nickelodeon Animation Studio SVPs Rich Magallanes and Jenna Boyd. The cable network would not comment on the layoffs beyond the statement it issued last week: “As announced, we are in the process of restructuring and there will be employees leaving the company as a result. We are so grateful for the contributions they have made to Viacom.”

Nickelodeon is the latest Viacom division to undergo layoffs as part of the companywide headcount reductions, joining sister networks MTV, VH1 and TV Land as well as Paramount Pictures. The Magallanes and Boyd departures were first reported by CartoonBrew.
