In September 2006, Ion Television launched Qubo, which was a three-hour block of programming (and accompanying digital subchannel) that originally aired on Wednesday through Friday afternoons – the E/I-compliant block has since moved to other time periods, and since settling on Friday mornings (airing from 8:00 to 11:00 a.m. Eastern Time, a time period during which most children are in school), in October 2012. However, on November 1, 2008, This TV launched airing a daily children's program block called Cookie Jar Toons (also known as This is for Kids); the three-hour block aired on Monday through Friday mornings as well as weekend mornings in most markets. This block was discontinued when Tribune Broadcasting assumed partial-ownership of This TV on November 1, 2013 (in favor of a three-hour Sunday-only E/I block), leaving Ion Television's Qubo as the sole remaining weekday children's block on American commercial broadcast television. Besides Qubo, there are only certain markets and syndicated channels that broadcast on weekday cartoons and broadcast it in the United States. The weekday cartoon came to an end on January 4, 2015 when the last-remaining weekday children's block on broadcast television, But - Qubo moved from Friday mornings-to-Sunday mornings under a new name, "Qubo Kids Corner". This had marked the end of a long era in weekday children's programming (including cartoons) going back to the early 1960s. Eventually "Qubo Kids Corner" discontinued thus returning on the weekday block, unlike its traditional schedule which ran Monday-Friday - it airs only on Wednesday-Fridays mornings. MundoMax airs one cartoon during late weekday afternoons in Spanish making the only two commercial networks to air cartoons while adhere the mandates, and the only Spanish network that is non E/I though it broadcast its E/I programming during weekday mornings and weekends. Due to the network closure of MundoMax this leaves only Qubo along with some local low power independent TV stations to air cartoons during the weekdays while adhering to mandates.
