Maria Bartiromo, one of the first women to become a star on television by reporting on business news, is leaving her longtime home at CNBC for its rival, the Fox Business Network.

CNBC confirmed the news Monday, thanking Ms. Bartiromo for her 20-year career at CNBC.

The network issued a statement: “After 20 years of groundbreaking work at CNBC, Maria Bartiromo will be leaving the company as her contract expires on November 24th. Her contributions to CNBC are too numerous to list but we thank her for all of her hard work over the years and wish her the best.”
