The history of the First Byurakan Survey carried out to search for AGN is shortly described. The sample completeness for different classes of objects: Sy1, Sy2, QSO, BL Lac objects is estimated as 0.6, 0.4, 0.4 and 0.6, respectively. The lack of radioquiet BL Lac objects as a whole class is shown. Different search procedures of AGN are compared, their perspectives are evaluated.
