Randy Falco, NBC Universal Television Group's president-chief operating officer, and David Zaslav, NBC Universal's president-cable distribution and new media, were both snatched away by rivals last week, but the media company has no immediate plans to replace either exec.

NBC Universal won't directly replace either Falco or Zaslav, instead relying on several execs to fill the void, Ad Age reports. Those execs with expanded duties include Jeff Gaspin, president, NBC Universal cable entertainment, digital content and cross-network strategy; Bonnie Hammer, president, USA Network and Sci-Fi Channel; Lauren Zalaznick, president, Bravo; Marianne Gambelli, EVP, NBC Universal sales and marketing; and Bridget Baker, EVP, NBC Universal Cable.

The staff changes come amid a battle for digital supremacy. Some within NBC U fear that Falco or Zaslav may court NBC U execs to join them. "A new CEO usually brings with them a CFO, an HR executive and their head of sales," one AOL insider said.

Part of the problem at NBC U, some industry insiders believe, is that there are too many high-level execs attempting to assert their control over the company. Ad Age quotes one media buyer as saying, "I heard there's a four-headed monster with Jeff Zucker, Beth Comstock, Randy Falco and Keith Turner. Now I guess it's a three-headed monster."
