Adding another block to the foundation of its nascent TV division, Polygram TV has tapped Saban Entertainment veteran Mark Lieber to spearhead the company’s push into the worldwide kidvid arena.As senior VP of children’s programming, Lieber will oversee the worldwide distribution of Polygram’s children’s programming. On the domestic side, Lieber will report to Bob Sanitsky, president of Polygram TV; on the international front, he’ll report to Stewart Till, president of international for Polygram Filmed Entertainment. At present, Polygram biggest presence in the kidvid arena is in international homevid distribution for such properties as “X-Men,” “The Mighty Morphin Power Rangers” and PBS’ “Wishbone.” Lieber is Sanitsky’s first major exec hire since the former top ICM agent was recruited by Polygram earlier this year to build a domestic TV operation for the Dutch-owned music and film giant. “In bringing on (Lieber), we’re rounding out the children’s distribution apparatus (Polygram) has built up internationally with a domestic specialist,” said Sanitsky. “With the boom in children’s programming, there’re more and more opportunities for suppliers but the dollars aren’t there. The only way you can make money is with an operation that can exploit properties on a global basis.” Lieber has spent the past six years with Saban, serving most recently as senior VP of domestic distribution. Prior to joining Saban, Lieber held sales and marketing posts with 20th Century Fox/Metromedia Producers, Fox/Lorber Associates and Goodman Entertainment Group.
