Shows that target this demographic focus primarily on entertainment and can range from comedic cartoons (with an emphasis on slapstick) to action series. Most children's television series targeting this age range are animated (with a few exceptions, perhaps the best-known being the long-running Power Rangers franchise), and many often specifically target boys (especially in the case of action series), girls or sometimes both. Efforts to create educational programming for this demographic have had a mixed record of success; although such series make up the bulk of educational programming on broadcast television, they also tend to have very low viewership.
