It’s really just a coincidence, but it was 20 years ago this week that I went full-time writing Daring Fireball (after writing the site in my spare time for 4 years). That feels like a long time ago. But it feels like yesterday, too. In my announcement, I wrote:

Daring Fireball is what I love to do.

That remains as true today than it was then. Whether you’re a longtime reader or a relatively new one, you might enjoy reading that piece from 20 years ago. So far, so good. (I’ve got some readers who were only small children when I wrote that. I occasionally hear from some who weren’t even born then.)

There might be other ways you can support my work directly in the future. But for now, the best way is to buy t-shirts and hoodies from my periodic sales. The current sale is going to end sometime tomorrow. If you’re seeing this post Sunday night and thinking about making a purchase, act now. If you’re seeing this Monday morning, you should really act now.

Ben Schoon, 9to5Google:

In March, a report revealed some of the internal cuts Samsung has been making for its mobile division, with the company initially concerned it could post an operating loss for the first time ever. It’s a big deal, as Samsung’s mobile (MX) division has historically always turned a profit.

A new report out of Korea (via Jukan) makes this seem all but certain.

Apparently, Samsung’s TM Roh, the head of the company’s mobile division, has expressed concerns of the “possibility of an annual deficit for the MX business unit.” Previously, those concerns came from speculation and outside parties, but with such a high figure in Samsung’s organization worried, it’s clear things are looking pretty bleak.

Back in 2013 analysts pegged the profit share of the handset industry at 70 percent for Apple and 30 percent for Samsung. A lot of other smaller companies sold a lot of other phones, but, so that analysis went, none of them made any profits. A lot of them were losing money. I linked to another such analysis in 2016 that pegged Apple’s share of phone profits at 104 percent, estimating that all other handset makers combined accounted for a 4% percent loss.

Doesn’t seem like much has changed since then. I prompted ChatGPT and Gemini today with this request: “Create a table of the world’s mobile device makers, ranked by profit and profit share of the industry.” ChatGPT pegs Apple’s profit share at 75–85%, Samsung’s at 10–20%, Huawei and Xiaomi in “low single digits”, and everyone else negligible. Gemini pegs Apple’s share at 85–90%, Samsung’s at 7–10%, Xiaomi at 1-2%, and everyone else negligible. This, despite both ChatGPT and Gemini agreeing that iPhones comprise only 20 percent of sales by unit. (Are ChatGPT and Gemini correct about the current profit share split of the mobile industry? I don’t know. But both cite sources in their answers, and it strikes me as very unlikely that their estimates are very far off.)

If Samsung posts a mobile division loss this year, it could be the case that Apple will capture 100 percent of the profits in the phone industry with just 20 percent of the sales.

Every single word of the November 2025 Financial Times report, which Mark Gurman derided as “simply false”, was, in fact, exactly correct.

My spitball idea for a generational law to keep more young people from ever starting a tobacco habit — and thus, nicotine addiction — would be through scaled taxation.
