CNN, under CEO Mark Thompson, is undergoing significant changes including laying off 100 employees to realign its newsroom structure and enhance digital presence. The network is shifting towards a more integrated digital service amidst declining traditional cable TV revenues. Thompson's plan includes leveraging AI, automation, and launching a new subscription service to generate over $1 billion. CNN is also restructuring news operations, combining TV and digital news teams, and focusing on video content to adapt to the evolving media landscape and address profitability challenges.
