Updated:From a sleepy phenomenon to the second biggest event next to the Super Bowl, Animal Planet's Puppy Bowl comes to the NASDAQ market site. As the event marks its 10th anniversary, the process of Puppy Bowl X together is quite amazing. This year's special will air six times over the course of 12 hours, starting at 3 p.m. ET, with new content added for each airing. Most importantly, Puppy Bowl raises awareness for rescue animals.
