In early sources "Wicca" referred to the entirety of the religion rather than specific traditions. In ensuing decades, members of certain traditions – those known as British Traditional Wicca – began claiming that only they should be termed "Wiccan", and that other forms of the religion must not use it. From the late 1980s onwards various books propagating Wicca were published that again used the former, broader definition of the word. Thus, by the 1980s, there were two competing definitions of the word "Wicca" in use among the Pagan and esoteric communities, one broad and inclusive, the other smaller and exclusionary. Although there are exceptions, among scholars of Pagan studies it is the older, inclusive use of the term which has gained wider usage. Conversely, in various forms of popular culture, such as television programs "Buffy the Vampire Slayer" and "Charmed", the word "Wicca" has been used as a synonym for witchcraft more generally, including in non-religious and non-Pagan forms.
