The nonlinear response of various materials extends beyond the illuminating beam. We present what is to our knowledge the first analytically tractable model for the dynamics of beams in partially nonlocal media. As far as an isolated beam is concerned, propagation is qualitatively the same, independently of the radius of nonlocality.
