This paper gives an overview of experiments on the fractional quantized Hall effect (FQHE). Two recent developments are discussed in some detail. One is the investigation of resistance fluctuations in narrow samples which gives evidence that the charge carried by a quasiparticle/quasihole excitation of the 1/3 FQH liquid is e/3. The other is on the influence of disorder in the two-dimensional electron system on the 1.5 FQH liquid and the re-entrant nature of the insulating state below and above it. The more recent observation, in this re-entrant insulating state, of an electric field induced transition into an {gt} 10 times more conducting state, accompanied by an onset of low frequency noise, is reviewed. It is confirmation that in low disorder samples the insulating and nonlinear transport characteristics around filling factor {nu} = 1.5 are indicative of a transition from the incompressible FQH liquids to a deformable Wigner solid.
