Soccer fan Neale Mahoney's goal when he subscribed to NBC's Peacock streaming service last year was to watch a single season of the Premier League. But he wound up paying for extra time.

"When I signed up last fall, I intended to cancel at the end of the season in May," Mahoney recalls. "But of course when it came to the summer, I forgot to cancel and I realized I paid for three extra months."
