In September 2005, the observing program of the Whipple 10 m gamma-ray\ntelescope was redefined to be dedicated almost exclusively to AGN monitoring.\nSince then the five Northern Hemisphere blazars that had already been detected\nat Whipple are monitored routinely each night that they are visible. Thanks to\nthe efforts of a large number of multiwavelength collaborators, the first year\nof this program has been very successful. We report here on the analysis of\nMarkarian 421 observations taken from November, 2005 to May, 2006 in the\ngamma-ray, X-ray, optical and radio bands.\n
