Under current mandates, all broadcast television stations in the United States, including digital subchannels, must show a minimum of three hours per week of educational children's programming, regardless of format. As a result, digital multicast networks whose formats should not fit children's programming, such as Live Well Network and TheCoolTV, are required to carry educational programs to fit the FCC mandates. The transition to digital television has allowed for the debut of whole digital subchannels that air children's programming 24/7; examples include PBS Kids Sprout, Qubo, PBJ, Discovery Family and Smile of a Child TV.
