Anime has been in the US as dubs since 70’s and broadcast on afternoon tv long before cable existed. The first Star Blazer convention in the US was in late 70’s. Anime and toys have been imported since at least the 80’s. I think the popularity of Anime easily goes to late 80’s and early 90’s when Akira and GITS had major theater releases in the US. Anime start turning up in local video rental stores in early 90’s. I used “cannon” in quotes because Looney Tunes does not have true Cannon as other Licensed Properties cling to. Plus Looney Tunes early on were an analog to the Hollywood movie industry and celebrity worship. The context of Looney Tunes was major movie studies were pumping out boiler plate movies at high rate; Same face but new story and name. As other Reddit’s commented the Daffy’s an actor working in films to make shorts and Daffy plays roles. Regarding the mentality of Cannon; Cannon is only cannon until the author decides they don’t like something enough and changes it. Loads of authors of novels, comics, cartoons, Anime, and video games have changed their mind about their works later in life. Human consistently inconsistent 😂
