Abstract
In 1992-2000, data on e+e− annihilation into hadrons were collected in the energy range with the CMD-2 and SND detectors at the VEPP-2M collider in Novosibirsk. The results of the R(s) measurements in these experiments are presented. The radiative return program at BaBar also allows to study low energy e+e− annihilation and overview of the results are presented in this paper.
