John McElwee, on his Greenbriar Picture Shows blog, recalls the horror of 1960s theatrical cartoon shorts:

These were dark days for animation. It’s a wonder our generation survived it. Never mind the damage sustained by Viet Nam and the drug culture. It was these cartoons that consigned many of us to a lifetime of sloth and indirection.

McElwee discusses the budgets these films were made under – and the meager profits they returned. No wonder they were soon to be history.
