The status of the determination of the Hubble constant is reviewed, setting out the evidence for the long distance scale with H_0=55+/-5. In parallel, various precepts said to favor the short distance scale with H_0>70 are discussed. The strongest evidence for the long scale are (1) the calibration of the peak absolute magnitude of type Ia supernovae with their Hubble diagram, (2) the distance to the Virgo cluster by six largely independent methods, and (3) field spirals binned by luminosity class. The three methods give H_0=56+/-3, 55+/-2, and 53+/-3 (internal errors). H_0 does not vary significantly over scales from 10-500 Mpc. Higher values of H_0 still in the literature are based on (1) an untenably small distance to the Virgo cluster, ...
