Massive stars of O, B, and Wolf-Rayet types are characterised by their strong, dense stellar winds. Throughout their lifetime their 
stellar  winds continue to enrich their surrounding with energy and matter, influencing galactic evolution significantly. Understanding 
stellar winds from massive stars is therefore important to understanding galactic evolution.

We aim to emphasize the importance of interferometric method in observing stellar winds from massive stars. We explore results from 
observations at various frequencies, from ultra violet to long-wave radio ranges. The phenomena shown by massive stars involve physical 
processes that took place in the parts of the winds at various radial distances from its base. In many cases these has revealed 
multiplicity of the massive star system.
