Arthur Marathon

The Arthur Marathon was an online and broadcast event from PBS KIDS. During the month of April 2019, visitors of the Arthur website could watch video clips and vote for three of their favorite Arthur shows out of a selection of 25 shows. On May 11, 2019, a marathon of the 25 episodes was shown on the PBS KIDS 24/7 TV channel and livestream. The top five results of the voting were revealed in a special countdown. Season 22 was promoted throughout the marathon. A rerun of the special “D.W. and the Beastly Birthday” concluded the marathon. The marathon was played again the next day on May 12, 2019.
