Bravo chief Lauren Zalaznick is adding a new title to her business card: head of Oxygen. With NBC Universal completing its $875 million purchase of the upstart cable network, it's posting one of its own on top, which means the sitting Oxygen head, the vivacious Lisa Gersh (seen here), will stick around for three months before, as Variety reports, she "take[s] a new position within NBC U." (The smoky-haired Zalaznick will continue as chief of Bravo and continue reporting to NBC Universal COO Jeff Gaspin.) At least that's the official story, though one NBC insider, who was on the periphery during the NBC-Oxygen buyout, suggests Gersh might already be exploring options back within Harpo – Oprah Winfrey's production unit that financed Oxygen – or they've been reaching out to her. Or maybe she's just keeping her options open?
