Katie Couric has expressed disappointment over CBS's decision to replace Norah O'Donnell with John Dickerson and Maurice DuBois as anchors of 'CBS Evening News,' arguing that this move makes the major evening newscasts male-dominated. Couric, who served as the CBS Evening News anchor from 2006 to 2011, highlighted that male writers can have 'blind spots' and stressed the importance of diversity in newsrooms, especially during a historic election period. She pointed out that while CBS has promoted women to executive roles, the leading editorial decision makers remain mostly men. Couric praised O'Donnell for her tenure and contributions to the network, noting her coverage of topics important to women. O'Donnell will transition to a role focusing on interviews and special projects at CBS.
