As a general purpose LHC detector, the Compact Muon Solenoid (CMS) was designed from the ground up to search for the Standard Model Higgs boson. Its individual subdetectors are optimized to effectively select Higgs signal out of large backgrounds, and when these subdetectors are combined via the Particle Flow reconstruction algorithm, they become even more powerful. Selected results of the Run 1 Higgs program highlight the capabilities of CMS: electromagnetic calorimeter resolution is critical for mass and differential measurements from decays to photon pairs, and evidence of decays to fermions illustrates the power of particle flow within jets. This program will continue to play a key role in future CMS algorithms, analyses, and detector upgrades. Developments for Run 2 will be reviewed, along with new technologies for the High Luminosity LHC and their impact on Higgs measurements.
