Traditionally, supernova surveys have drawn their samples by monitoring pre-selected lists of host galaxies. More recently, some surveys have made efforts to ignore host properties when selecting candidates, but because of limited resources they must usually add additional selection criteria, such as the color or light curve shape of the transient, in order to select the best targets for a specific study. Since 2004, we have conducted a search for supernovae that is designed to select targets irrespective of their host environment, and we have spectroscopic classifications for all of the new transients detected. Here we report on the host galaxies of first 72 supernovae detected by ROTSE-IIIb as part of the Texas Supernova Search and the ROTSE Supernova Verification Project. The supernova sample includes everything from perfectly normal Type Ia and Type II, to spectroscopically peculiar events, to several of the most luminous supernovae ever found. We compare multi-band photometry and spectroscopy of the host galaxy sample to the larger galaxy population. We cannot securely identify host galaxies brighter than -10 mag absolute for four of our discoveries, which suggests that these may be hostless, "tramp supernovae."
