The development of the Very Long Baseline Interferometry as a space geodetic technique started in the 1960’s. The R&D institutes in the United States and Japan developed several practical geodetic VLBI systems, and have been upgrading them with the advancement of technology. The VLBI operations, for instance, observation, data processing, and analysis had been implemented by some regional communities such as the Japan-US Joint Experiment and the Geodetic VLBI Community in Europe. Since the International VLBI Service for Geodesy and Astrometry (IVS) was established in 1999, the operations have been conducted under a global framework. This report reviews the history of VLBI development, looks over the status of the present VLBI operations of IVS to study how the countries in the world contribute to IVS, and gives an outline of the future VLBI concept (VLBI2010). Furthermore, an issue into the geodetic VLBI community in Japan is raised.
