  In this overview talk, I give highlights of the first three years of the LHC
operations at high energy, spanning heavy-ion physics, standard model
measurements, and searches for new particles, which culminated in the discovery
of the Higgs boson by the ATLAS and CMS experiments in 2012. I'll discuss what
we found about the properties of the new particle in 10 months since the
discovery and then talk about the future LHC program and preparations to the
2015 run at the center-of-mass energy of ~13 TeV. These proceedings are meant
to be a snapshot of the LHC results as of May 2013 - the time of the
conference. Many of the results shown in these proceedings have been since
updated (sometimes significantly) just 4 months thereafter, when these
proceedings were due. Nevertheless, keeping this writeup in sync with the
results shown in the actual talk has some historical value, as, for one, it
tells the reader how short is the turnaround time to update the results at the
LHC. To help an appreciation of this fact, I briefly summarize the main changes
between May and September 2013 in the Appendix.
