user22761: Question for old animators at Hanna Barbara: 1960s - 1980s. Do Hanna Barbara cartoons use 30 frames/s or 24 frames/s, and did they draw most animation on 2s for real 15 frames/s or 12 frames/s?
I guess 30 frame/s (15 frames/s on 2s) because US company make cartoons for TV (US TV during that time is NTSC ≈ 30 frames/s). 

user27435: As far as I can remember Hanna Barbara was not even on 2s!  They would hold frames for seconds at a time.  I often felt cheated on the hair bear bunch.

For a standard Disney feature, the film would be projected at
  the standard 24 frames per second with each frame having different
  animation. Planned animation provided for fewer frames, so that
  instead of each frame having a new image, frames would be repeated two
  or three times, resulting in just twelve or eight different frames per
  second.
This experimental approach is showcased in UPA’s most stylized
  cartoon, Gerald McBoing Boing, for which they won an Academy Award in
  1951. However, Hanna-Barbera adapted the technique out of necessity.
