Edutainment
Some television shows incorporate a considerable degree of historical or factual information while attempting to make the presentation or framing of such content entertaining or exciting. By making learning seem "exciting" they can be said to stimulate curiosity. The presence of edutainment is especially evident in children's television series, such as Sesame Street, Dora the Explorer, and Teletubbies. Discovery Channel is also known for its various shows that follow that theme, including MythBusters. Sometimes these programs may be more entertaining than educational, and may replace educational shows in the televisions program lineup. The History Channel has transitioned from producing primarily factual and historical documentaries, to more sensational, dramatic, and supposedly entertaining programs, with educational content a secondary concern.
The Children's Television Act of 1990, which was first fully enforced in 1996, requires broadcast television stations in the United States to carry a minimum of three hours of "educational/informational" programming geared directly at children. The move prompted an exodus of non-educational children's programming to cable television and largely failed in its efforts to expand the amount of educational television on the airwaves (in fact, children's television in general has declined significantly on broadcast television since the act was imposed, although it can be argued that the E/I regulations could very well be the only thing keeping children's television on broadcast airwaves in the 2010s).
