Markarian Survey (or the First Byurakan Survey, FBS) was the first systematic objective prism survey in the world and the first survey for active galaxies. 1500 UV-excess galaxies were discovered, later named Markarian galaxies. Its digitized version, DFBS, was created in 2002-2005 and the Armenian Virtual Observatory (ArVO) was founded in 2005 as well. Byurakan Astrophysical Observatory (BAO) always has been famous with its surveys and discovery of new objects, such as Markarian, Arakelian and Kazarian galaxies, Shahbazian groups, Parsamian nebulae, etc.
