Blue circles show all satellites, violet squares (green triangles) show those of just the MW (M31).  Of these 56 satellites, only 4 are star-forming/gas-rich: LMC ($\mstar=1.5\times10^9\msun$) and SMC ($\mstar=4.6\times10^8\msun$) around the MW, LGS 3 ($\mstar=9.6\times10^5\msun$) and IC 10 ($\mstar=9\times10^7$) around M31.  At $\mstar<8\times10^7\msun$, 50 of 51 satellites are quiescent, and at $\mstar<9\times10^5\msun$ \emph{all} are quiescent.  Error bars show 68\% uncertainty based on the observed counts.
