While radio and optical telescopes can resolve and monitor the individual blazar images, Fermi's LAT cannot.
The extreme brightness and variability of blazars result from a chance orientation that brings one jet almost directly in line with Earth.

For example, the rapid development ofradio astronomy after the Second World War gave rise to the designations radio galaxy (1940s)--galaxies which produced unusually large amounts of radio radiation--quasar (early 1960s)--mysterious point-like sources of radio radiation in the sky--and blazar (mid-1970s) quasars which showed dramatic variations in brightness.
