EXCLUSIVE: Nickelodeon’s SVP Development & Original Programming Tracy Katsky is leaving the youth-oriented cable network after 4 years. Katsky’s contract was up, and she opted not to renew it. Katsky will be leaving at the end of the week, and I’ve already heard her name mentioned in the mix for a couple of high-profile executive and producing jobs around town. Before joining Nickelodeon in 2007, Katsky was SVP of development for HBO Independent Prods., SVP and head of comedy for Fox and SVP and head of comedy for Regency TV.
