In the music industry, the term one-hit wonder is used to describe an artist primarily known for a sole hit single. While no singular established criterion exists to classify an artist as a one-hit wonder, the frequently-cited technical description of a one-hit wonder in the United States defines a hit single as one which hits the top 40 of the national singles chart, the Billboard Hot 100. Accordingly, Billboard journalist Wayne Jancik defines a United States one-hit wonder as "an act that has won a position on Billboard's national, pop, Top 40 just once." Using this definition, artists are therefore classified as one-hit wonders based solely on Billboard Hot 100 chart performance—other factors such as success in other territories, additional hits on other Billboard genre-specific charts, membership in more prominent bands or musical groups, critical acclaim, and influence are not considered.
