Under his leadership, E!'s ad revenue has grown exponentially in the past 14 years, and our expanding roster of properties will be well served by his wealth of television industry experience."

"It is an incredible opportunity to take on a new leadership role for one of the most respected names in cable," said Cassaro. "I look forward to working with Amy and the entire Comcast family as we continue to build on the impressive growth that Comcast has made in network ad sales."
