Though often referred to by the public as The Carpenters, the duo's official name on authorized recordings and press materials is simply "Carpenters". During a period in the 1970s when louder and wilder rock was in great demand, Richard and Karen produced a distinctively soft musical style that made them among the best-selling music artists of all time.
Carpenters' melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary genres. Carpenters had three #1 singles on the ''Billboard'' Hot 100 and fifteen #1 hits on the Adult Contemporary chart (see The Carpenters discography). In addition, they had twelve top 10 singles (including their #1 hits). To date, Carpenters' album and single sales total more than 100 million units.
