The Large-Scale Structure of the Universe offers us a window to better understand current challenges in cosmology. In particular, over the last two decades the measurements of Baryonic Acoustic Oscillations has settled as one of the most reliable cosmological probes. These primordial sound waves leave an imprint on the distribution of observable matter, which can be used as a standard ruler to measure the expansion history of the Universe. I will review the final SDSS results on BAO measurements and also present the recent and ongoing Dark Energy Survey BAO analysis. These two analyses will represent the final picture in terms of BAO before the next generation of surveys: DESI and Euclid.
