Jo Ann Ross, a pioneering figure in the television industry and the first woman to lead a broadcast network’s ad sales efforts, is retiring from her role as chairman of Paramount Global’s ad sales division at the end of April. During her tenure, Ross played a pivotal role in shaping the advertising landscape for primetime broadcast programs and forged enduring relationships with key advertisers. Paramount CEO Bob Bakish praised Ross’s contributions, including her leadership in integrating the company’s ad sales organization and reimagining its upfront format. Ross joined CBS in 1992, gradually rising to become the longest-tenured sales head in broadcast TV history. She oversaw the development of innovative ad formats, such as product integrations and in-show segments, while also championing diversity and female representation in media and entertainment.
