Deadline: In one of the biggest personnel changes in the broadcast comedy business in years, network TV’s preeminent comedy development executive, CBS EVP Wendi Trilling, is leaving after a stint at the net spanning a quarter of a century. She will depart at the end of her contract in June after opting not to renew it. “After more than 24 years at CBS, it’s time to take a breath and look toward a new challenge,” said Trilling.
