Answer by taking a quote from the following article:

Burton was born to American parents at the U.S. Army Landstuhl Regional Medical Center in West Germany. His mother, Erma Gene (nee Christian), was a social worker, administrator, and educator. His father, Levardis Robert Martyn Burton, was a photographer for the U.S. Army Signal Corps at the time he was stationed at Landstuhl. Burton and his two sisters were raised by his mother in Sacramento, California.

Burton was the host and executive producer of Reading Rainbow starting in 1983 for PBS. The series ran for 23 seasons, making it one of the longest-running children's programs on the network. The series garnered over 200 broadcast awards over its run, including a Peabody Award and 26 Emmy Awards, 11 of which were in the Outstanding Children's Series category. Burton himself won 12 Emmy awards as host and producer of the show.  After Reading Rainbow went off the air in 2006, Burton and his business partner, Mark Wolfe, acquired the global rights to the brand and formed RRKIDZ, a new media company for children. Reading Rainbow was reimagined as an all new application for the iPad in 2012, and was an immediate success, becoming the number-one educational application within 36 hours. At RRKIDZ, Burton serves as co-founder and curator-in-chief, ensuring that the projects produced under the banner meet the high expectations and trust of the Reading Rainbow brand.  On May 28, 2014, Burton and numerous coworkers from other past works started a Kickstarter campaign project to bring back Reading Rainbow. To keep with the changing formats to which young children are exposed, his efforts are being directed at making this new program web-based, following the success of the tablet application he helped create in recent years. His desire is to have the new Reading Rainbow be integrated into the classrooms of elementary schools across the country, and for schools in need to have free access. The Kickstarter campaign has since raised over $5 million, reaching triple its goal in only three days.

Did Burton do any other work related to the series after it went off of TV?
