We summarise some of the works that have been carried out on the interstellar medium (ISM) with the Giant Metrewave Radio Telescope (GMRT) in the last few years. These include, (i) determination of the fraction of neutral hydrogen in unstable phase, (ii) turbulence in the ISM investigated through radio continuum and neutral hydrogen, (iii) turbulence in the ionised ISM giving rise to variations in pulsar dispersion measures, (iv) probing the denser ISM near the Galactic centre, (v) studies of HII regions and (vi) confirmation of new supernova remnants near the Galactic centre.
