Using accurate photo-z's and extrapolations of the counts at faint fluxes we resolve with unprecedented detail the build-up of the mid-IR background across cosmic ages. We find that ~50% and ~80% of the 24mic background intensity originate from galaxies at z<~1 and z<~2 respectively, supporting the scenario where highly obscured sources at very high redshifts (z>~2) contribute only marginally to the CIB.
