  We present new results from the VLBA 2 cm Survey, an imaging survey of active
galactic nuclei (AGN) at sub-milliarcsecond resolution. We extend the
structural variability monitoring program of more than 130 extragalactic
parsec-scale radio jets from over 170 AGN to a total of eight years. The sample
is explored further in time for all sources, and intensively for individual
objects. We report new detailed results on the compact sources III Zw 2, AO
0235+16, and NRAO 512.
