Recent experimental data that establish properties of multiple parton interactions in hadron-hadron collisions are reviewed. The emphasis is on the recent D0 measurements the fraction of events with double parton (DP) scattering produced in the photon+3-jet and photon+2-jet events as well as measurement of azimuthal decorrelations in these events. The DP fractions, the azimuthal cross sections and also effective cross section, a process-independent scale parameter related to the parton density inside the nucleon, are measured in three intervals of the second (ordered in pT) jet transverse momentum. Some ongoing studies and prospects are also discussed.
