Through its association with the Young British Artists and the Turner Prize during the 1990s, in popular usage, particularly in the United Kingdom, "conceptual art" came to denote all contemporary art that does not practice the traditional skills of painting and sculpture. One of the reasons why the term "conceptual art" has come to be associated with various contemporary practices far removed from its original aims and forms lies in the problem of defining the term itself. As the artist Mel Bochner suggested as early as 1970, in explaining why he does not like the epithet "conceptual", it is not always entirely clear what "concept" refers to, and it runs the risk of being confused with "intention". Thus, in describing or defining a work of art as conceptual it is important not to confuse what is referred to as "conceptual" with an artist's "intention".
