During the last two years, observations of the molecular cloud content of early type galaxies have drastically changed our view of these systems as inert gas-poor galaxies with little or no star formation activity. Systematic surveys in the CO (J=1-0) line (Wiklind and Henkel, 1988a,b; Thronson, private communication) have shown that an IR selected sample of early type galaxies contains typically 107-108 Mo of molecular hydrogen gas. This is similar to the typical HI masses found in these galaxies (Knapp et al., 1985; Wardle and Knapp, 1986).
