The terms internet tribe or digital tribe are used as slang terms for unofficial online communities or organizations of people who share a common interest, and who are usually loosely affiliated with each other through social media or other Internet routes. The term is related to "tribe", which traditionally refers to people closely associated in both geography and genealogy. Nowadays, it looks more like a virtual community or a personal network and it is often called global digital tribe. Most anthropologists agree that a tribe is a (small) society that practices its own customs and culture, and that these define the tribe. The tribes are divided into clans, with their own customs and cultural values that differentiate them from activities that occur in 'real life' contexts. People feel more inclined to share and defend their ideas on social networks than they would face to face.
The term "tribe" originated around the time of the Greek city-states and the early formation of the Roman Empire. The Latin term "tribus" has since been transformed to mean "A group of persons forming a community and claiming descent from a common ancestor" (Oxford English Dictionary, IX, 1933, p. 339, as cited in Fried, 1975, p. 7). As years passed by, the range of meanings have grown greater, for example, "Any of various systems of social organization comprising several local villages, bands, districts, lineages, or other groups and sharing a common ancestry, language, culture, and name" (Morris, 1980, p. 1369). Morris (1980) also notes that a tribe is a "group of persons with a common occupation, interest, or habit," and "a large family." Vestiges of ancient tribe communities were preserved in both large gatherings (like football matches) and in small ones (like church communities). Even though nowadays the range of groups referred to as tribal is truly enormous, it wasn't until the industrial society eroded the tribal gatherings of more primitive societies and redefined community.
