Popular culture (commonly known as pop culture) is the totality of artistic products, ideas, perspectives, attitudes, memes, images and other phenomena that the average person of any nation or group is likely to have encountered or been influenced by. In developed countries, cultural products are often disseminated by market-driven mass media (at least from the early 20th century onward). For this reason, it sometimes comes under heavy criticism from various scientific and non-mainstream sources (most notably religious groups and countercultural groups) which deem it superficial, consumerist, sensationalist, and corrupted.

It is manifest in preferences and acceptance or rejection of features in such various subjects as cooking, clothing, consumption, and the many facets of entertainment such as sports, music, film, and literature. Popular culture often contrasts with the more exclusive, even elitist "high culture", that is, the culture of ruling social groups, and the low or folk culture of the lower classes. The earliest use of "popular" in English was during the fifteenth century in law and politics, meaning "low", "base", "vulgar", and "of the common people"; from the late eighteenth century it began to mean "widespread" and gain in positive connotation. (Williams 1985). "Culture" has been used since the 1950s to refer to various subgroups of society, with emphasis on cultural differences.
