I'd be willing to be that the slogan 100% Angus beef is an Angus cross that might only be 50% true Black Angus.
When my grandpa who has been dead close to 40 years started building his cattle herd, buyers wanted registered Herefords. He was selling registered yearling Hereford bulls in the 1940's for $2000 per head.
Now the rage is for Angus beef and the price reflects it.
