摘要
Abstract This article provides a 20-year, apples-to-apples update of the National Television Violence Studies. Using the same sampling procedures and codebook, we coded 765 primetime television programs and movies airing on 21 broadcast and cable networks. Results suggest the prevalence of violence has increased slightly, but the number of programs saturated with violence has experienced a more significant increase. This appears to be driven by an influx of highly violent movies airing in primetime on cable channels. Although some contextual variables suggest slight improvements in terms of negative consequences for violence, the overwhelming majority of violent television programs and movies do not feature anti-violence themes. Implications for social cognitive, cultivation, schema, transportation, and media vividness theories are discussed.
