> What is pre-Code Hollywood? The quickest definition is this: “pre-Code” refers to an era in motion pictures from the arrival of sound (aka ‘talkies’) in 1927 to the mandatory enforcement of the Motion Picture Production Code in July 1934. This era is notable for while being censored, it is not as severely censored as the films that follow that July 1934 date.

Which besides answering the literal question, explains what motivated the code and why pre-code movies are worth watching.
The site in general contains a lot of valuable content about these movies.
The answer is not on the page linked and the topic is obscure. The "ending" to an "enjoyable article" is not the answer to the title question. It's obvious why "Pre-Code" is contextually confusing.
Based on that context my first thought was "Pre-Code? Like, before CGI really took off, right? So like late 90's and earlier" :)
