The group enjoyed success during the 1990s, with nine top-ten hits on the Billboard Hot 100, including four number-one singles: "Creep", "Waterfalls", "No Scrubs", and "Unpretty". The group also recorded four multi-platinum albums, including CrazySexyCool (1994), which received a diamond certification from the Recording Industry Association of America (RIAA). TLC became the first R&B group in history to receive the million certification from the Recording Industry Association of Japan (RIAJ) for FanMail (1999).

A girl group is a music act featuring several female singers who generally harmonize together. The term "girl group" is also used in a narrower sense in the United States to denote the wave of American female pop music singing groups, many of whom were influenced by doo-wop and which flourished in the late 1950s and early 1960s between the decline of early rock and roll and start of the British Invasion. All-female bands, in which members also play instruments, are usually considered a separate phenomenon. These groups are sometimes called "girl bands" to differentiate, although this terminology is not universally followed.
