Murdoch Murdoch was / is a much-loved alt-right(*) cartoon series steeped in 4chan's Politically Incorrect board, /pol/. It ran from 2015 - 2021 and was created by the three anonymous 'Murdochs': the main creative 'Murdoch Murdoch' (usually just 'Murdoch'), 'Murdoch Chan', and 'Dr Murdoch'.
Initially the series was just 'sh*tposting', and / or mocked leftists and degeneracy, but it soon came to express a deep care for the situation of the European people. The show centers whites and serves to help acknowledge, express, orient and sometimes metabolize what we are faced with. It confronts a lot of uncomfortable issues directly and, usually, compassionately. The show is irreverent, playful, and humorous, but fundamentally sincere and at times very strongly felt.

For more, see their early Radix Interview, informal /pol/ AMA (search for 'yoEK' for the Murdochs' responses), Reddit AMA, and their multiple audio AMAs (one, two, three, four - transcriptions of varying quality). The earlier AMAs answer more basic questions.

If you're looking for a place to start, perhaps try Murdoch's own suggestions, or the "house's choice" of Essential Episodes.

One thoughtful testimony to their impact:

Q: Is MM safe for kids?
A: No, but they'll watch and probably enjoy it anyway. The series comes from an 18+ board, and the language is about rough high-school (middle-school?) level, ie 'R'-rated with a lot of racial epithets, although the narrated episodes have no offensive language or imagery (except a small amount of nudity in 'The Last Son of the West'). Overall, the series is probably not suited for homeschooled, Christian seven-year-olds. Some parents have said they watch (presumably some) episodes with their kids, and the Murdochs acknowledge that not everything is for everyone but in general seem to be happy for whatever kids are permitted to watch: (from: AMA 2, starting at 6:20).
