When was the red card for deliberate hand ball in the penalty area introduced?

Answer 1

I actually don't know, but I will correct what appears to be a slight misunderstanding of the rule. A red card isn't shown for any deliberate handling in the penalty area; it's for denying a goal or obvious goal-scoring opportunity by committing a foul. This doesn't necessarily have to be in the penalty area, and it's possible to have it happen in the penalty area without being an obvious scoring opportunity (if, for example, several more defenders are nearby).
