Brian L. Roberts, chairman and chief executive officer of Comcast Corporation, said, "2017 is off to the fastest start in five years. We are reporting outstanding growth at Cable and particularly NBCUniversal, which delivered 14.7% revenue growth and 24.4% Adjusted EBITDA growth. These impressive results were fueled by exceptionally strong film performance, increased affiliate and retransmission revenues at our TV businesses, and continued growth in Theme Parks. Cable operations had a terrific quarter, driven by strength in high-speed Internet and business services revenue growth, as well as positive video, all highlighted by overall customer relationship net additions of 297,000, a 10% increase compared to last year. These results were balanced with financial discipline, which contributed to solid revenue and Adjusted EBITDA growth. The transition from Neil Smit to Dave Watson has gotten off to a very successful and seamless start, and with our teams executing well across all of Comcast NBCUniversal, I am excited about our momentum headed into the rest of 2017 and beyond."
