I want to know the answer to the following question:
Which group was created after a Senate hearing on comic books content?
All the background I'm provided with is that "Following a sales peak in the early 1950s, the content of comic books (particularly crime and horror) was subjected to scrutiny from parent groups and government agencies, which culminated in Senate hearings that led to the establishment of the Comics Code Authority self-censoring body.". Is that enough to answer the question?
Answer: yes
