EXCLUSIVE: NBC chairman Bob Greenblatt didn’t want to make major changes to his development team until after the upfronts next month. But I hear at least one move is already in the works: that NBC’s head of comedy Jeff Ingold is expected to leave the network, and hot Sony TV comedy executive Tal Rabinowitz is in line to replace him. Also it’s looking increasingly likely that 20th Century Fox TV EVP Jennifer Nicholson Salke could join her close friend Greenblatt at NBC as entertainment president after the upfronts.

Rabinowitz has been SVP comedy at Sony TV and a rising star at the studio, overseeing some of the highest-profile comedy projects including The Big C, one of the last series developed and picked up by Greenblatt while he was entertainment president at Showtime. In addition to comedy, Rabinowitz has overseen digital development and programming for Sony. She started her career at the weblet WB. Rabinowitz and husband Terence Carter are poised to become quite the power TV network couple: he heads the drama development department at Fox.

As for Ingold, he’s served as EVP comedy at NBC since 2008. There has been speculation he might eventually join Bill Lawrence’s production company at Warner Bros as the two have a great relationship going back to the days when Ingold served as the exec on Lawrence’s NBC comedy Scrubs. Ingold has been at NBC for more than a decade and has served as a comedy executive at NBC/UMS since 2002. He also has a longtime relationship with Greenblatt as David Janollari’s assistant at the duo’s production company, Greenblatt Janollari Studio.
