The Network That Lived on Desktops
You run the largest social network in the world, about to sell shares to the public for the first time. Nearly all your revenue comes from ads shown beside the news feed on computer screens. More than half your users now reach you on phones, where you show almost no ads and where your app is slow.
Do you reorganise the whole company around the phone, rebuilding your apps and putting ads into the mobile news feed itself, while your existing business is still on the desktop?
The situation
It is the first half of 2012. Your company runs a social network used by 845 million people a month. You make most of your money from ads, and those ads appear in a column beside the news feed on computer screens, where advertisers can buy them through a self-service system. The business is large, profitable and still growing. In a few months you will list your shares on a stock exchange.
Your users are leaving the desktop. More than 425 million of them reached the network through mobile apps or mobile websites in December 2011, and that number is growing faster than your audience as a whole. On a phone there is no column beside the feed. You show almost no ads there. Your own prospectus, filed in February, says plainly that you do not generate meaningful revenue from mobile and that your ability to do so is unproven. A later amendment adds that your daily users are growing faster than the number of ads you deliver, because more of their activity is on phones.
What you know
For about two years your mobile apps have been built largely with web technologies, so that most of the product can be written once and run on any phone, and updated without waiting for app-store approval. The approach was meant to save effort and keep you independent of the companies that control the mobile operating systems. In practice the apps are slow, freeze and crash, and users rate them poorly. Your engineers believe a native rebuild, written separately for each operating system, would be much faster, but it means rewriting the product and maintaining several codebases.
You have one mobile ad format, promoted posts that appear inside the feed, and early tests show they get far more clicks than desktop ads. But ads inside a personal stream of friends’ news are intrusive in a way that ads in a side column are not, and a phone screen shows one item at a time.
Your organisation is built around the desktop. Mobile is a separate team; most product groups ship features to the website first and to the apps later, if at all.
What you don’t know
You do not know whether users will accept ads in their mobile feed, or how many would leave. You do not know whether advertisers, used to buying desktop ads, will pay for mobile ones, or how to measure their value. You do not know whether web technologies will soon catch up with native apps, making a rewrite wasted effort. And you do not know how public investors, who will see your results every quarter from now on, will react if mobile growth drags down revenue per user.
The voices in the room
Some argue that the web approach is right in principle and that its problems are temporary; abandoning it would mean betting on the operating-system companies, who are also potential rivals. Others argue that the phone makers are the real threat, and that the company should build its own presence on the phone. A third group points to the desktop business that pays for everything and to the IPO, and argues for caution: keep the mobile feed clean, protect the column ads and buy promising mobile apps as insurance. The last group says the company is in danger of becoming a desktop company in a mobile world, and that half-measures will not do.
What happened
The company was Facebook. In 2012 it reversed its approach to mobile almost completely. It rebuilt its iPhone app natively, releasing the new version in August, and followed with Android. Mark Zuckerberg, its chief executive, said at the TechCrunch Disrupt conference that September that betting too much on HTML5 rather than native apps had been one of the company’s biggest strategic mistakes, and that it had cost about two years. He described Facebook as now a mobile company, and said that mobile users were more likely to use it daily than desktop users.
The organisation changed with the product. Facebook moved from functional groups to product groups, each responsible for its product on every device, and dissolved the separate mobile team into them; a product director described the aim as making every engineer a mobile engineer.
The ads moved into the feed. Promoted posts inside the mobile news feed, already running before the IPO, were reported to draw about twice the clicks of desktop ads and nearly three times the price, and were grossing about $500,000 a day by July 2012. In October Facebook opened mobile app install ads, which let developers pay to promote their apps in the feed, to all developers.
The IPO itself went badly. Shares priced at $38 on 18 May 2012 fell to about $17.55 by early September, as investors worried about mobile. Then the numbers turned. Mobile accounted for about 23 percent of Facebook’s advertising revenue in the fourth quarter of 2012, and about 53 percent a year later, when mobile ad revenue passed $1.25 billion in a single quarter.
The alternative of owning a layer of the phone was tried too, and failed. In April 2013 Facebook launched Home, software that replaced an Android phone’s home screen, along with a phone made by HTC. Reviews were poor, sales of the phone were reported to be very small, and the effort was quietly wound down. By 2025 Meta, as the company was renamed, had revenue of $201 billion, almost all of it from advertising, and 3.58 billion people a day using at least one of its apps, nearly all of them on phones.
Judging the decision apart from the outcome
The process was strong in the way it confronted evidence. The company’s own data showed users moving to phones, its own prospectus named the risk, and its own engineers knew the apps were poor. Rather than defending the earlier web-technology decision, which would have been the path of sunk costs and pride, the leadership reversed it publicly within months. It also changed the organisation, not just the product, recognising that a mobile team inside a desktop company would always be second, a lesson familiar from the innovator’s dilemma.
The decision was made under the pressure of a public listing, which made it harder. A company focused on the quarterly revenue that analysts watched might have protected the desktop column ads; Facebook accepted a period in which its share price halved. The willingness to bear that cost depended partly on the founder’s voting control, which shielded the decision from investors’ short-term reactions. That shield was a condition of the decision’s quality, and it is not available to most companies.
The decision also had costs that the revenue figures do not show. Putting ads inside a personal feed on a device carried everywhere, and building products for daily use on that device, intensified the competition for attention that later drew criticism from users, researchers and regulators. Those consequences were partly foreseeable in 2012, and they belong in any full judgement, though they do not change the commercial verdict.
What a good process would have weighed
The web-first path had genuine merit, independence from platform owners and a single codebase, but the evidence from users said it was not working, and the company could not afford to wait for the technology to improve. The own-platform path addressed a real strategic weakness, dependence on the operating-system companies, and Facebook’s later failure with Home suggests users did not want a social network to become their phone. Protecting the desktop was the comfortable choice, and the history of platform shifts suggested it was the most dangerous. The chosen path accepted short-term pain, a public admission of error and a more intrusive ad format in exchange for following users where they had already gone.
Sources and limitations
The numbers on users and the risk to revenue come from Facebook’s own prospectus. Zuckerberg’s statements are from a public interview after the decisions were made, and describe his own judgement of the earlier strategy. The figures on the early performance of mobile feed ads come from a third-party agency study and press reports and were not disclosed by Facebook. The sales of the HTC phone were reported by a single unnamed source. The point about the founder’s control of votes is the author’s interpretation of why the decision could withstand the fall in the share price, as is the judgement of the decision’s wider costs.
The reveal
Facebook's shift to mobile, 2012
Make the phone the primary product. Rebuild the apps natively for each platform, move engineers into product teams that all build for mobile, and put ads directly into the mobile news feed.
Paid off
The company rebuilt its apps natively in 2012, reorganised so that every team built for mobile, and expanded ads in the mobile news feed. Mobile went from about 23 percent of advertising revenue at the end of 2012 to 53 percent a year later. A separate attempt to own a layer of the phone, in 2013, failed.

The forces pulling at the people deciding
-
The desktop business was profitable, growing and well understood. Mobile users were growing faster but earned almost nothing. Every rational short-term signal pointed to protecting the desktop, which is exactly how established companies miss shifts.
-
The company had spent about two years building its mobile apps in web technology. Abandoning that work meant admitting a costly mistake in public, just as investors were judging the company for the first time.
-
Users and advertisers had to move together. Ads that annoyed users could shrink the audience advertisers were paying to reach; an audience with no ads could not pay for the service.
-
As a newly public company, every quarter's revenue would be scrutinised. The temptation was to optimise for the number analysts watched rather than for where users were going.
-
Earlier platform shifts, from mainframes to personal computers and from desktop software to the web, had punished leaders who stayed loyal to the old screen. The base rate was not on the side of caution.
Signals that were visible at the time
- More than half of the network's 845 million monthly users were already using it on mobile devices, and mobile users were growing faster than users overall.
- The company's own prospectus warned that it did not generate meaningful revenue from mobile and that the shift could hurt its results.
- The number of daily users was rising faster than the number of ads shown, because more of the activity was on phones.
- The existing apps, built largely in web technology, were widely criticised as slow and crash-prone, and app-store ratings were poor.
- Early tests of promoted posts inside the mobile feed were drawing more clicks than desktop ads.
When your users move to a new screen, follow them before your revenue does, and rebuild the product for that screen rather than shrinking the old one to fit.
