Measurements of the electron-positron continuum in ALICE

The status of the analysis of electron-positron pairs measured by ALICE in pp collisions at $\sqrt{s}=7$ TeV and central Pb-Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=2.76$ TeV is presented. Key questions and the main challenges of the analysis are discussed on the basis of first raw invariant mass spectra for both collision systems.
