The Salsa boom some years ago mainstreamed Salsa dancing to the extent that it is obviously the leading Latin dance. One result is that Ballroom studios now make it clear that what they teach are "Ballroom-Latin" dances - including Rumba, Cha Cha, Bolero, and other long-time "Ballroom-Latin" dances. Another element is that Salsa itself has been expanding and incorporating Mambo and other facets. Today "Salsa" is more and more "Salsa-PLUS" - Bachata, Cumbia, etc. Lots of wonderful dancing from which to choose to move your groove.
