Kosowski fills the news director spot left vacant by broadcast veteran Monika Diaz earlier this year. Diaz declined to say why she left the newsroom, though sources told a prominent industry gossip blog that it was the result of a new no-profanity rule within Nexstar’s newsrooms.
Kosowski has a lengthy resume of experience within local and national newsrooms: He served as an assistant news director at NBC’s Washington owned-and-operated station WRC-TV (Channel 4) in the late 90s before joining San Francisco ABC station KGO-TV (Channel 7) at the turn of the millennium.
He left KGO to work as the news director of Boston’s then-NBC affiliate WHDH (Channel 7) before moving to New Jersey to join CNBC as an executive producer.
Kosowski’s six-year stint with CNBC ended when he became the vice president of news and digital content at KDVR (Channel 2), a Tribune-owned Fox affiliate. He joined Nexstar in 2016 and has moved from station to station within the company since then.
