Sludge content (also known as content sludge and overstimulation videos [1] ) 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. [2] Common attention-grabbing videos include repetitive mobile gameplay (notably of the endless runner mobile game Subway Surfers ), ASMR/oddly satisfying clips, and cooking videos. [3] 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 ), [4] Reddit posts read by an artificial voice, [2] and videos made by other TikTok users. [3]
Sludge content has been labelled as overstimulating and addictive. [1] [3] [5] The genre has been described as reflecting and contributing to declining attention spans, [5] [3] though these interpretations have been criticized. [3] Sludge content may also lead to normative dissociation, which can be soothing. [6]
The concept of sludge content originates with methods used to subvert copyright detection tools, particularly on Family Guy "funniest moments" compilations on YouTube. [3] Editing techniques such as frequent jump cuts, overlaid unrelated clips, and cropping have increased the longevity of copyright-violating videos on YouTube.
The proliferation of sludge content has been attributed to its ease of creation and its profitability. [7] [3] TikTok's "duet" feature, in which a creator can post a video side-by-side with a video from another creator, [8] has been cited as priming viewers for this form of multitasking. [3] Users have noted the proclivity of TikTok's recommendation algorithm to increasingly show such videos to users; the process of steadily consuming more sludge content has been popularly described as a "pipeline" (often called the "Family Guy pipeline" due to the series's ubiquity in such content). [4] [7] [9] Sludge content has also been described as a form of escapism. [10]
Psychologist Natalie Coyle analyzed the videos and determined that the external media increases receptiveness through the concept of "visual tactility". [11] Digital media researcher Bjørn Nansen opined that the phenomenon should not be unexpected given the prevalence of media multitasking outside of TikTok. [12]
SYBO Games, the developers of Subway Surfers, referenced sludge content on the TikTok account for the game and attributed Subway Surfers' resurgence to sludge content. [2]
Accounts from content creators including British power metal band DragonForce, political commentator Hasan Piker, and Andrew Tate have posted videos on TikTok featuring sludge content. [13] [14] Companies, including Visible, Pepsi, and Tums, have used sludge content in advertisements. [15] The New Zealand National Party used sludge content to promote their policies in the 2023 general election. [16]
A 2020 study found that engaging with various digital media on multiple devices simultaneously may worsen attention and recall in young adults. [17] Concern has been raised over the popularity of such split-screen content with young children in Generation Alpha. [18]
