Part 2. What Is a Business Model? — A Tool for Dissecting Payment Habits

A Genealogy of Payment Habits — A Historical Hintbook for New-Content Business Models Part 2

“What About the Business Model?”

Someone asks that question in the meeting room.

You have explained the platform, the format, and the target audience. Whether the proposal is twenty pages or fifty, the question inevitably appears.

“What about the business model?”

Then something strange happens. No matter how new the content, the moment you explain its business model, you choose among models that already exist: subscriptions, advertising, free-to-play purchases, gacha, season passes, or a combination of them.

Why?

The answer is the subject of this entire book. Before reaching it, however, we need a tool: a language for reading history and dissecting the spaces occupied by past payment habits.

This chapter introduces that tool.

A Business Model Is Not a Revenue Model

First, one confusion must be cleared up.

A business model and a revenue model are different, yet planning teams often mix the two. When someone says, “Our business model is a subscription,” they are describing a revenue model.

A revenue model explains how money will be collected.

A business model is much broader. It includes who provides what to whom, what they receive in return, and how the arrangement can endure. That is why a business-model canvas contains producers, partners, channels, value propositions, customer segments, cost structures, and revenue streams.

Within that broad business model, this book focuses on payment habits: why people came to pay in a particular way, how the habit formed, and how it transferred.

This is the most important question for a new-content planner. Before choosing the shape of a revenue model—subscription, advertising, or gacha—understand the habit-space in which that shape can operate.

Think of the revenue model as a vessel and the payment habit as the liquid filling it. However fine the vessel, it remains empty without the liquid.

Eight Questions — A Tool for Dissecting Payment Habits

The most useful tool for reading a payment-habit space is simple: eight questions.

Who pays for what, why, when, how, where, how much, and how many times?

These questions began as a business-model planning checklist. Here they point in the opposite direction. Instead of designing something new, they become an anatomical tool for reading past payment habits.

Let us examine each one.

Who — The Person Who Pays and the Person Who Uses

The first question looks simple but is not: Are the payer and the actual user the same person?

Often, they are different.

A parent pays for an educational app used by a child. A company buys workplace software used by employees. A teenager uses a parent's card for an idol fandom. A husband pays for an OTT subscription watched mainly by his wife.

This division is decisive because payers and users judge value differently. A parent pays for educational effect rather than merely an app the child enjoys. A company may buy software whose report format meets corporate standards rather than software employees find easier.

Ask the same question of history: Who paid for this product, and who actually used it? Were they the same group? If not, how did that separation later change?

What They Value — The Core of Value

People do not pay for every feature of a product. They pay for something specific within it.

On a music-streaming service, the motive may not be music itself. It might be offline storage, ad-free listening, or the recommendation algorithm. Even within one service, payment motives differ from person to person.

The question matters especially at historical turning points. What did people pay for in the late-1990s packaged PC game market? The game content itself? The physical possession of a CD? Or the product authentication and multiplayer access that came with purchase?

Different answers lead business models to evolve in different directions.

Why Pay — The Payment Threshold

Free alternatives are everywhere. People still need a reason to open their wallets. Creating that reason is the core of payment design.

Business-model planning calls this the value proposition. This book asks a slightly different question: Is there already a space in which people are opening their wallets? Can the new content land there?

Creating an entirely new reason to pay is nearly impossible. Delivery fees feel ordinary today, yet the habit took years to form. Baedal Minjok and Yogiyo did not succeed by inventing payment for delivery. They transferred an existing habit of paying for the value of time—taking a taxi or paying more at a convenience store—into the context of delivered food.

When reading history, ask: when this payment first appeared, which existing habit-space supported it?

When — The Terrain of Time

Payments occur in patterned moments. An arcade coin is paid “immediately, here and now.” A subscription is paid regularly every month. Gacha is purchased impulsively in a moment of excitement.

These temporal structures are not mere conveniences. They create psychologically different payment experiences, and those experiences land in different habit-spaces.

Change the “when,” and the business model changes. The move from buying a CD—one-time ownership—to subscribing to streaming—monthly recurrence—changed not only the form of content but the temporal structure of payment. History shows why that transition met resistance and how it was accepted.

How and Where — Payment Friction

Inserting a coin into a machine, swiping a card at a counter, or pressing one button in an app are different forms of “how and where.”

Less friction makes payment easier, but reducing friction is not always unambiguously good. Standing before a card terminal and entering a PIN preserves the awareness that real money is being spent. One-click purchases and automatically renewed subscriptions weaken that awareness.

This reduction in friction helped create the mobile gacha market. One reason small purchases feel psychologically “small” is the near absence of payment friction.

When reading history, ask how the physical and psychological friction of payment changed, and who benefited from the change.

How Much — The Evolution of Payment Units

Price is not merely a number. It is framing.

The same amount is perceived differently depending on its unit. That is why subscription marketing so often says “the price of one coffee a day.”

Historically, payment units have tended to shrink: an LP album (20,000–30,000 won), a single CD (5,000 won), a digital song (700 won), then monthly streaming (9,900 won). This was not a simple sequence of price reductions. Each payment unit landed in a different habit-space.

Buying one song monetized the immediate feeling, “I like this song.” A monthly subscription moved payment toward “a way of life that includes listening to music.” Not only the vessel but the nature of the value inside it changed.

How Many Times — The Depth of the Relationship

Is the payment one-time, recurring, or lifelong?

A packaged game was basically a one-time purchase. An MMO subscription created a relationship renewed every month. Gacha can theoretically repeat without limit. A season pass defines a three-month period and fills it densely.

“How many times” determines more than revenue frequency. It structures the relationship between producer and consumer. A one-time sale exchanges “I give you this; you give me money.” A subscription promises, “We will continue this relationship.”

The changing form of that promise is another axis traced by this book.

The Map Created by the Eight Questions

The questions are not independent. Their intersections create a terrain map.

An arcade game's payment terrain in the 1980s might look like this:

Who: teenage boys, paying directly rather than through parents
What: displaying technical mastery and ranking within a peer group
Why: the desire for “one more round”; greater skill increased the value of each coin
When: after school, on weekends, or on days they skipped tutoring
How and where: insert a coin and begin immediately, inside the physical arcade
How much: 50 won per play, rising to 100 won in the early 1990s; 50 won then bought one snack
How many times: until the money ran out or the risk of being caught by parents grew too high

Successful and failed business models separate on this map. Games that landed well in the space dominated arcades. Those that ignored its grammar were rejected despite technical excellence.

What does the terrain map for your new content look like?

The Most Important Separation — Payer ≠ User

“Who” is especially important because misreading this separation destabilizes the entire business model.

Consider historical cases where it proved decisive.

The console hardware market. In the 1980s and 1990s, parents bought consoles while children used them. Nintendo read the separation precisely. Children needed to find the game fun, but parents made the purchase decision. Nintendo's marketing therefore repeated the language of “fun for the whole family”: enjoyment for children and reassurance for parents. This dual language formed its early marketing strategy.

Enterprise software. The separation is extreme. IT procurement staff or executives buy office software, while ordinary employees use it every day. Microsoft Office retained dominance partly by exploiting this division. Even if employees preferred an easier program, buyers had little reason to change while corporate standards were aligned with Office.

The K-pop fandom economy. At a certain point, album purchasing shifted toward fandom. Another separation emerged within it: dedicated fans who actually pay—core fans, organized devotees, buyers of dozens of albums seeking admission to fan signings—and casual listeners who learn about the artist because that fandom exists. Record labels manage both groups. They sell limited merchandise and privileged access to core fans while offering streaming and music itself to casual listeners at close to no cost. This structure made Korea's music industry one of the world's most distinctive fandom economies.

Failure Cases — When the Separation Is Missed

What happens when this division is ignored?

The lesson of the Sega Saturn. Sega launched the Saturn in Japan in 1994, with hardware capable of competing with Sony's PlayStation. The problem was the United States. At E3 in May 1995, Sega unexpectedly announced that the Saturn was available immediately for $399. Sony took the same stage and answered with one line: “$299.”

The surprise launch cost more than a $100 price difference. Major retailers such as Walmart and KB Toys, given no advance notice, protested; some stopped carrying Sega products altogether. The Saturn became a more expensive machine available at fewer stores. Dedicated fans still sought it out, but for payers comparing price tags in stores during the holiday season, it was difficult to find and cost $100 more.

Sega looked only at enthusiastic users willing to spend. Sony also looked at the conditions in which payment actually occurred—price and distribution. The result is familiar.

News media's failed digital transition. In the early 2000s, many newspapers failed at digital paywalls partly because they misread this separation.

In the print era, the payer was an individual or corporate subscriber, while the consumers were the subscriber, family members, or office colleagues.

But a print subscription included other reasons to pay: the physical habit of daily delivery to one's door, the social signal that “this household subscribes to a newspaper,” and the morning routine of reading it with coffee.

Those reasons disappeared in the digital transition. The news content was the same, but the surrounding habit-space changed completely. It was no longer “a newspaper read digitally” but “information freely accessible anywhere, anytime.”

Search engines and portals, not newspapers, read the change fastest. They distributed content for free and captured advertising revenue. Those who produced the news lost money; those who distributed it earned money.

The platform changed the “who.” The payer moved from reader to advertiser. The user remained the reader, but the paying party changed. Newspapers unable to adapt could not avoid restructuring.

The educational-app paradox. In the mid-2010s, many startups entered the market with the promise that “children learn while having fun.” Children liked the apps, session time was high, and reuse rates were respectable. Paid conversion nevertheless fell short.

The split explains why. Children used the apps, but parents paid. Parents did not ask merely whether a child enjoyed an app, but whether it genuinely helped. A fun app and an educationally effective app look very different through the eyes of child and parent. Design language aimed only at the user—the child—lacked a message capable of persuading the payer.

Apps that recognized the division reversed the result with learning reports such as “Your child focused for thirty minutes today,” curriculum-alignment labels, and weekly achievement summaries. These are not features for children; they are language that reassures parents. Survivors such as Duolingo speak both layers at once: like a game to the child, like education to the parent.

Two Kinds of Payment-Habit Space

Payment-habit space has two layers.

Layer 1: the user's habit-space. How were consumers already consuming similar things? Which forms were familiar? How often and in what context did they consume them?

Layer 2: the payer's habit-space. How was the actual payer already spending on a similar category? At what price, how often, and for what reason?

New content must land on both layers. If users cheer but payers remain unconvinced, the business model does not operate. The reverse is equally true: payer interest is useless if users never approach the content.

The strongest business models make the two layers one person: an adult paying for their own leisure, an adult paying hourly at a PC café, or an employee subscribing to music streaming. The spaces merge, allowing much simpler design.

Separation creates complexity but also opportunity. New connections become possible. Cases that use this division creatively appear throughout the book.

Reading a Historical Transition with Eight Questions — iTunes

To see the tool in action, let us dissect the iTunes example from the prologue.

Immediately before iTunes appeared in 2003, the music industry's map looked like this.

Previous habit-space, the CD era

Who: music fans from their teens to thirties, buying directly; sometimes parents bought for them
What: a whole album and the act of owning an artist's “complete collection”
Why: the sensation of ownership; a displayed CD collection as identity; value as physical merchandise
When: a visit to a record store; a new-release date was an event
How and where: cash or card at the record-store counter
How much: 10,000–15,000 won per album, a high unit price
How many times: several albums a year, mainly new releases from favorite artists

When Napster collided with this terrain, it erased “why” and “how much”: any desired song, free. Downloads preserved a feeling of ownership but removed the reason to pay. It tried and failed to build a new habit-space.

iTunes was different.

The iTunes design

Who: the same music fans themselves
What: not a whole CD but one favorite song—the pleasure of selection
Why: ownership by song, instant satisfaction, and reassurance that it was legal
When: immediately, at the moment “I like this song,” without visiting a store
How and where: one click, anywhere in front of a computer
How much: one dollar, or about 1,000 won—less than a coffee
How many times: whenever desired

iTunes changed “what,” “how much,” and “when.” Each change inherited a pattern already present somewhere else: single CDs had established song-level sales, music vending machines and coin karaoke had established micropayment, and software sales had established immediate downloads.

Nothing was completely new. iTunes recombined fragments of existing habit-spaces. That was why it succeeded.

Carrying the Tool into History

We now have an anatomical tool.

Who, what, why, when, how, where, how much, and how many times—plus the most important lens, the separation between payer and user.

With this tool, we enter history.

From the next chapter onward, we will explore specific industries and periods. The recurring questions remain the same.

Where did this payment habit come from? What space did it inherit? What made the connection possible? Who entered without that connection and failed?

At the end of each chapter, we will ask questions for your new content.

Which existing payment-habit space can our content enter? Are the user's and payer's habit-spaces the same or different? Did a similar transition occur before? Why did it succeed or fail?

The answer is in history—not exactly, but as a hint.

Hints from This Chapter — Checkpoints for New-Content Planners

Checkpoint 1: Map the payment-habit space before choosing a revenue model.

Before saying, “Our business model is a subscription,” ask whether the target users already pay for something by subscription. What is it, and how close are we to that space?

Checkpoint 2: Consider the payer and user separately.

If they are the same, simplify. If they differ, satisfy both groups. Remember which historical cases succeeded or failed because of this separation.

Checkpoint 3: Choose the payment unit and temporal structure consciously.

“How much” and “how many times” are not mere pricing policy. Consider the psychological structure they create and the established habit-space supporting it. A familiar unit is usually the best starting point.

Checkpoint 4: Find failure cases first.

If a similar attempt occurred before, its failure matters as much as a success. Failure usually comes from a mismatch with the payment-habit space. Avoiding the same mismatch is the first reason to study history.

The next part begins with the oldest form of payment habit: when people first began paying for “pleasure,” and why that first payment-space became the prototype for every later digital-content business model.
