THE VIMOS VLT DEEP SURVEY (VVDS) IS A MAJOR REDSHIFT SURVEY OF THE DISTANT UNIVERSE, AIMED AT STUDYING THE EVOLUTION OF GALAXIES, LARGE SCALE STRUCTURES AND AGNS OVER MORE THAN 90% OF THE AGE OF THE UNIVERSE. A TOTAL OF 41000 SPECTRA HAVE BEEN OBSERVED SO FAR. FROM THE FIRST EPOCH OBSERVATIONS CONDUCTED WITH VIMOS, WE HAVE ASSEMBLED ~11000 REDSHIFTS FOR GALAXIES WITH 0 £ Z £ 5 SELECTED WITH MAGNITUDE IAB £ 24 IN AN AREA 3.1 TIMES THE AREA OF THE FULL MOON. WE PRESENT EVIDENCE FOR A STRONG EVOLUTION OF THE LUMINOSITY OF GALAXIES AND SHOW THAT GALAXIES ARE ALREADY DISTRIBUTED IN DENSE STRUCTURES AT Z ~ 1.5. THE HIGH REDSHIFT POPULATION OF ~1000 GALAXIES WITH 1.4 £ Z £ 5 APPEARS TO BE MORE NUMEROUS THAN PREVIOUSLY BELIEVED. AS THE SURVEY CONTINUES, WE ARE ASSEMBLING MULTI-WAVELENGTH DATA IN COLLABORATION WITH OTHER TEAMS (GALEX, SPITZER-SWIRE, XMM-LSS, VLA), AS WELL AS EXPANDING TO LARGER SCALES (~100 MPC) TO PROBE THE UNIVERSE IN AN UNPRECEDENTED WAY.
