Some of the key benefits of mass media upon society are education and public service. Mass media is an effective tool for education, able to reach many more people than schools.
Educational television networks, such as The Discovery Channel, are examples of this benefit in practice.
Mass media as a public service manifests itself in, for example, television networks such as PBS (The Public Broadcasting Service). Founded in 1969, networks of its type are independent from advertising revenue and therefore more at liberty to create in-depth and well-researched educational or news programs.
One of the best-known and most successful PBS education programs is Sesame Street, which set out to teach children literacy, numeracy, problem-solving, socialization and other basic life skills.
