Serialisation

What it is

A hit show delivers an audience once. A serial delivers the same audience tomorrow, and the difference between those two sentences is most of the economics of broadcasting.

The technique is old, older than radio, and print serials were doing it in the nineteenth century. What changed in 1929 was that a broadcaster applied it to a fixed slot on a national network. Amos 'n' Andy went national on NBC that year, after a local Chicago run from 1928, and Wu's reading of it is that the comedy was the surface and the continuing plotline was the machine. Once a story is engineered not to resolve on schedule, the schedule itself acquires value, because the audience has been given a reason to be somewhere at a particular time that has nothing to do with liking the network. That is how a single evening slot became the industry's most valuable property. See prime time for what got built on top of it.

The proof that this was a mechanism rather than the luck of one programme is that it transferred. Irna Phillips applied the identical technique to daytime and produced the daytime serial, aimed at women at home during the day, which is where the soap opera comes from. Two entirely different audiences, two entirely different hours, one structural device, and it worked in both places. A device that only works once is a hit. A device that works wherever it is pointed is a technology.

What serialisation is usually explained by is a psychological claim, and it is worth being precise about how much weight this page puts on it. The mechanism generally offered is the idea that an unresolved task is held in mind more readily than a resolved one, so a story deliberately left open occupies attention until it closes. This vault takes that from Adam Alter's Irresistible, where it appears as one of six ingredients of behavioural addiction, and it has not been verified here against the original experimental literature. The vault note it comes from is unreviewed, and the concept it depends on has no page on this site. It is a plausible account of why the technique works. It is not the reason to believe the technique works, which is the commercial record.

That distinction matters more than usual here, because serialisation is exactly the kind of thing a writer reaches for when a business practice needs to sound like neuroscience. The honest position is that broadcasters discovered empirically, and very quickly, that people return for an unfinished story, and that psychology arrived afterwards with candidate explanations rather than in advance with a prediction.

The technique did not stop. The most recent evidence for it is a reversal: streaming services that spent a decade releasing entire seasons at once have moved back toward weekly episodes, which is the 1929 mechanism rediscovered under a different name by an industry that had briefly abandoned it. That is an observation about industry practice rather than a measured finding, and it should be read as one.

In effect

Research: the explanation this page declines to lean on

The standard psychological account of serialisation is the Zeigarnik effect, the claim that an interrupted or unfinished task is retained in memory more readily than a completed one, and, downstream of it, Adam Alter's "unresolved tension", listed in Irresistible as the fifth of six ingredients of behavioural addiction. Alter's chapter attaches the idea to cliffhanger-driven media and to autoplay features that begin the next episode before the current one has settled.

This site has not verified the original Zeigarnik literature, has not written a page for it, and does not treat it as established. It is recorded here because a reader who meets serialisation elsewhere will almost certainly meet this explanation attached to it, and because knowing which half of a claim is documented history and which half is borrowed psychology is the whole point of a page like this one. The history is solid. The mechanism is a hypothesis in a trade book.

Everyday life: the episode that ends in the wrong place

The recognisable form is an episode that stops mid-scene, or a season that closes on a question. Nobody experiences this as a scheduling decision. It is experienced as annoyance followed by anticipation, and then, a week later, as an appointment that gets kept.

The design tell is that the interruption is placed rather than found. A story with a natural ending point can be cut before it, and the choice of where to cut is the product decision. It is the same decision Irna Phillips was making in the 1930s, made with better tools.

Commerce: the number Netflix released, and the one it did not

Netflix released all thirteen episodes of House of Cards season one simultaneously on 1 February 2013, and the all-at-once release became the defining argument against serialisation for roughly a decade. The statistic that circulated in support of it is worth pulling apart, because this vault checked it.

The widely quoted claim is that 61 per cent of viewers binged the show. That figure is not a House of Cards poll. It comes from a survey commissioned by Netflix and conducted by Harris Interactive between 25 and 27 November 2013, among 1,496 US adults who stream weekly, and what it found was that 61 per cent of online television streamers watch two to three episodes in one sitting at least every few weeks. That is a general habits question with a very loose definition of bingeing, released to support a commercial decision Netflix had already taken. Treat it as company marketing data, not research.

There was an independent survey of the actual show, and it is a different and smaller number. Cowen and Company, a financial-services research firm, found in February 2013 that roughly 10 per cent of subscribers had watched House of Cards, averaging about six episodes each. Six of thirteen is not a completed binge. It is a serial being watched at a serial's pace, on a platform that had removed the schedule.

What it does not say

It is not a research claim. The vault records it as not-a-research-claim, and the page is built from broadcast history and industry practice. No controlled study appears on it, and none is being implied.

Nobody invented it, and Wu did not coin it. Concepts/Serialisation.md records the originator as unknown, with the date 1929 attached to the broadcast application rather than to the technique, which is older. Wu dates and interprets. The interpretation, that serialisation rather than comedy was the real innovation, is his argument and should carry his name in the sentence.

It does not establish that unfinished stories are held in memory differently. The Zeigarnik effect and Alter's "unresolved tension" are the usual explanation, this site has not verified either, and the vault note behind them is unreviewed. Anyone building a product on that mechanism is building on an unverified claim from a trade book, not on this page.

It does not support the 61 per cent binge figure. That number is Netflix-commissioned, was collected months after the release it is used to describe, and answers a different question. The independently produced figure for the same show is about 10 per cent of subscribers, averaging six episodes.

The weekly-release reversal is an industry observation, not a measurement. No figure on this page establishes that weekly release outperforms simultaneous release, and this site has not seen one that does.

Who developed it

No single originator. The technique predates broadcasting; what has a date is its application to a national radio schedule, and that date, 1929, comes from Tim Wu, whose The Attention Merchants supplies both the history and the claim that serialisation rather than the comedy was the invention. Irna Phillips demonstrated that the mechanism was not tied to the evening by building the daytime serial on it, which is the strongest single piece of evidence that a mechanism is what it was.
