There are reports of significant changes in ratings for several evening news programs, including those of CBS, NBC, and ABC. The ratings swings are also being observed in morning shows, such as 'GMA', 'Today', and 'CBS Mornings', as well as in cable news networks like CNN, MS NOW, and Fox News. The cause of these swings is uncertain, with some outlets mentioning the Iran conflict as a possible factor, but the impact on each network's ratings is unclear.
