Sludge content
Sludge content (also known as content sludge and overstimulation videos) is a genre of split-screen video on short-form video platforms like TikTok and YouTube Shorts.
Characteristic of sludge content is unrelated, attention-grabbing side content, meant to increase viewer retention. Common attention-grabbing videos include repetitive mobile gameplay (notably of the endless runner mobile game Subway Surfers), ASMR or oddly satisfying clips, and cooking videos. Sludge videos typically feature one panel of main content with audio, often copyrighted material. Common copyrighted material include television episodes (notably of the adult animated television series Family Guy), Reddit posts read by an artificial voice, and videos made by other social media users.
Sludge content has been labelled as overstimulating and addictive. The genre has been described as reflecting and contributing to declining attention spans, though these interpretations have been criticized. Sludge content may also lead to normative dissociation, which can be soothing.
