The Network and the Photo App
You run the world's largest social network, weeks before a public stock offering. People are moving their social lives to phones, and your mobile app is weak. A tiny photo-sharing app is growing explosively on phones.
The photo app's founders are raising money at a valuation of about half a billion dollars. Do you buy them, build your own, or let them be?
The situation
It is April 2012. Your company runs the largest social network in the world, with hundreds of millions of users. It is weeks away from a public stock offering, and investors are focused on one weakness: the network was built for desktop computers, and people are moving their social lives onto phones, where your app is slow and clumsy.
A photo-sharing app, launched eighteen months ago for one phone platform, is growing explosively. It lets people take photos, apply filters and share them with followers. It has about thirty million users, a team of about a dozen people and no revenue. A week ago it launched on the other major phone platform and gained a million new users there in about a day. Its founders are raising money at a valuation reported at around half a billion dollars, and other large companies are interested.
What you know
Social networks become more valuable as more people use them, and the number of distinct social behaviours worth building is limited. This app has captured a behaviour, sharing photos from phones, that your network should own and does not. Your engineers are capable, but building a copy would take time and might not attract the same community.
What you don’t know
You do not know whether the app’s growth will last, whether it can make money, or whether its users would stay if it became part of your company. You do not know how regulators will view large companies buying young rivals.
The voices in the room
Some argue the price would be absurd for a company with a dozen employees and no revenue, weeks before your public offering. Others argue that if a rival buys it, or it grows into an independent competitor, it could be very damaging, and that buying a network effect is cheaper than fighting one. Some suggest a minority stake.
What happened
The companies were Facebook and Instagram. On 9 April 2012 Facebook agreed to buy Instagram for about $1 billion in cash and stock, and committed to running it as an independent app. Internal emails later released by a congressional committee showed Mark Zuckerberg describing young networks such as Instagram as potentially very disruptive and discussing acquisitions as a way to neutralise competitors, before clarifying that he had not meant to buy them to stop them competing; these are discussed in detail in the Instagram emails memo.
The Federal Trade Commission reviewed the deal in 2012 and did not challenge it. Instagram grew past one billion and then three billion monthly users, adding features such as Stories in 2016, and became one of Meta’s most valuable businesses. In December 2020 the FTC sued Facebook, arguing that the Instagram and WhatsApp acquisitions were anticompetitive. In November 2025 a US judge ruled that the FTC had not shown that Meta currently held monopoly power.
Judging the decision apart from the outcome
As a business decision, the process was strong. Facebook identified a real strategic weakness, mobile, and a forming network effect it could not easily build. It moved quickly, at a price that looked high in 2012 and very low later, and it chose to preserve what users valued by keeping the app independent. In transaction cost terms, it bought something no amount of internal engineering could produce: a community and a habit.
The case is also an ethical one, which this page cannot settle. A decision can be strategically excellent for one company and costly for others. Buying a fast-growing rival reduces competition, which is why regulators later challenged it. A court ultimately found the regulator had not proved its monopoly case. The tragic choice idea is relevant here: judging the decision means saying for whom it was good.
What a good process would have weighed
Building a copy risked failure and delay. A minority stake would have left Instagram free to be bought by someone else or to compete. Ignoring it risked losing mobile social behaviour. The main costs of buying were the price, the integration risk and regulatory exposure, which was low at the time and grew later.
Sources and limitations
The price, dates and later events are from Facebook’s announcement, the documents released in 2020 and the memo on this site, which covers the emails in detail. The descriptions of the emails are summaries. The legal outcome is as reported in November 2025. Judgements about competitive harm are contested, and this page does not take a position on them.
The reveal
Facebook and Instagram, 2012
Buy the app for about $1 billion and keep it running as a separate product.
Paid off
The network bought the app in April 2012 for about $1 billion in cash and stock. The app grew past a billion users and became one of its most valuable businesses. The purchase later became the centre of an antitrust challenge, in which a court ruled in 2025 that the regulator had not shown the company currently held monopoly power.

The forces pulling at the people deciding
-
Internal messages later released showed intense attention to the young app as a threat. Buying a rival before it can become a full competitor is a response to rivalry that changes the market itself.
-
Social apps grow more valuable as more people use them. A network that had already formed around photos on phones would be very hard to dislodge by building a copy.
-
Building a rival product would take time and might never capture the same community. Buying acquired a position, users and a habit, that could not be built at any price.
-
A choice with costs for others
What was strategically sound for the buyer reduced competition in social media, a cost borne by users and potential rivals. Regulators, years later, argued the purchase was anticompetitive; a court ultimately did not agree.
Signals that were visible at the time
- The app was growing extremely fast on phones, where the network's own app was weak.
- It had just launched on the second major phone platform and gained a million users there within a day.
- Its founders were raising money and other large companies were interested.
- The network's public offering made mobile weakness a pressing concern for investors.
When a network effect is forming around something you lack, the price of buying it now is usually lower than the price of competing with it later.
