Status and Prospectives of Hadronic Cross Section at Low Energy

Abstract

In this talk I will review the experimental status and the prospects for the future of $\sigma (e^{+}{e}^{-}\to hadrons)$ at low energy. The recent preliminary results obtained by KLOE and BABAR collaborations using the radiative return will be also discussed.
