We consider generalizations of the standard model (SM) which are based on the gauge symmetry SU(n)c⊗ SU(m)L⊗ U(1)N. Although the most interesting possibilities occur when n=3, we will consider also the cases n=4,5 both with m=3,4. Models with left-right symmetry, horizontal symmetries and the possible embedding in a larger group (grand unification scenarios) are briefly discussed.
