As part of the launch of Twitch Creative, Twitch.tv hosted a nine-day marathon of Bob Ross' The Joy of Painting series which started on October 29, 2015 in commemoration of what would have been his 73rd birthday.[24][25][26] Twitch reported that 5.6 million viewers watched the marathon, and due to its popularity, created a weekly rebroadcast of all 31 seasons of The Joy of Painting to air on Twitch each Monday, and will have a marathon of episodes each October 29th. A portion of the advertising revenue has been promised to charities, including St. Jude Children's Research Hospital.[27]
