iPhone. eBay. GraphQL. PostgreSQL. These names break the basic English rule that proper nouns start with a capital letter. They're common enough now that we don't notice — but they're a recent phenomenon, and the choices behind them are deliberate.
Here's the history of unusual brand capitalization, why companies choose these patterns, and how to handle them in writing.
The basic English rule (and its long exceptions)
Standard English capitalization for proper nouns: the first letter is uppercase. Microsoft, Google, Coca-Cola, Sony, Toyota.
This rule has exceptions even in traditional English. e e cummings deliberately styled his name in lowercase for poetic effect. k.d. lang uses lowercase styling. Authors and artists have always taken license with the rules.
But these were individual stylistic choices, not corporate naming conventions. The widespread phenomenon of brands deliberately styling themselves with non-standard capitalization is a product of the late 20th and early 21st centuries.
The early outliers: 1990s tech companies
A few notable early examples:
eBay (1995)
Pierre Omidyar founded the company as "AuctionWeb" in 1995 and renamed it "eBay" in 1997. The lowercase e was a deliberate visual choice — it evoked email addresses (also lowercase) and signaled "internet company" before that became a saturated genre. The styling has been preserved through every brand evolution since.
iMac and iPhone (1998, 2007)
Apple released the iMac in 1998. The lowercase i was chosen by Apple to suggest "internet" (the iMac was an early consumer PC designed for easy internet access), and later expanded to mean "individual," "instruct," "inform," "inspire" (per Steve Jobs's introduction). The convention spread to iPod (2001), iPhone (2007), iPad (2010), and dozens of other products.
The pattern became so identified with Apple that other companies began using i prefixes too — usually as a kind of stylistic imitation.
jQuery (2006)
John Resig released jQuery in 2006 with a lowercase j at the start. The reason: it looked like a fluent code identifier (camelCase) rather than a brand name. The styling matches programming conventions for variable and function names, which made it feel like a tool rather than a product.
The 2000s and 2010s explosion
Through the 2000s, unusual capitalization became almost expected for tech brands. The conventions diversified:
Camel-case brand names
Names with internal capitals: PayPal, YouTube, QuickBooks, WordPress, JavaScript, SharePoint, OneDrive, FaceTime, iCloud, AirPods.
These names typically combine two words without a space. The internal capital marks the word boundary while the seamless joining suggests a unified concept rather than two separate words.
Lowercase-first brand names
Names that deliberately start with a lowercase letter: iPhone, iPad, iMac, eBay, jQuery, mIRC, iMessage, iOS, tvOS, watchOS, macOS, visionOS, iLife, nginx.
The lowercase first letter signals "tech product" or "software" — these names don't behave like normal proper nouns.
Acronym-heavy brand names
Names that incorporate uppercase acronyms in non-standard ways: GraphQL, PostgreSQL, MySQL, SQLite, jQuery, NumPy, PyPy, TensorFlow, WebGL.
These names embed an acronym (SQL, QL, py, GL, etc.) inside a longer name, with the acronym preserved in uppercase. The capitalization signals the acronym's identity.
All-lowercase brand names
Names styled entirely in lowercase: airbnb, thoughtbot, github (sometimes — the company often capitalizes as GitHub formally), npm, yarn.
This signals "casual" or "modern minimalist" branding. Often these companies will style their name lowercase in marketing material but capitalize it normally in body text (Airbnb is widely written with a capital A in journalism even though Airbnb's own design lowercases it).
Why companies choose these patterns
Several motivations recur:
1. Visual distinctiveness
A name that breaks the capitalization rules stands out in body copy. Among a sea of properly-capitalized "Microsoft" and "Oracle" mentions, "iPhone" catches the eye. This was particularly valuable in the early internet era when brands were competing for cognitive shelf space.
2. Trademark distinctiveness
Trademarks must be distinctive to be registered. A name with unusual capitalization is more obviously a brand and less easily confused with a common noun. Apple is dictionary; iPhone is unmistakably a product.
3. Cultural positioning
Unusual capitalization signals "tech," "modern," or "casual." Banks and law firms still use traditional capitalization (JPMorgan Chase, Goldman Sachs, Latham & Watkins) because the formality is part of the brand. Tech companies use unusual capitalization in part to differentiate themselves from these older industries.
4. Acronym preservation
For technical products built on or implementing standards (SQL, GL, QL), the acronym is sometimes preserved in uppercase even when surrounded by lowercase letters. GraphQL reads as "the GraphQL standard"; graphql would lose that signal.
5. Word combination indication
For two-word names without a space, internal capitals signal the word boundary. PayPal reads as "Pay" + "Pal"; paypal reads as a single mysterious word.
How to write these names in your copy
The rule: preserve the brand's canonical capitalization. Don't "fix" it to match style guide rules.
Correct (preserves brand styling):
- "The iPhone was released in 2007."
- "GraphQL is a query language for APIs."
- "eBay went public in 1998."
- "Many developers prefer PostgreSQL to MySQL."
Incorrect (overrides brand styling):
- "The Iphone was released in 2007."
- "Graphql is a query language for APIs."
- "EBay went public in 1998."
- "Many developers prefer Postgresql to Mysql."
The exception that some style guides recommend: when a brand name with a deliberately lowercase first letter starts a sentence, capitalize it like a normal sentence. So "eBay went public in 1998" would become "EBay went public in 1998" at the start of a sentence.
This is controversial. Most modern publications now preserve the brand styling even at the start of a sentence — "eBay went public in 1998" reads as fine. The older rule was created when these brands were unusual; now they're so common that readers don't expect the sentence-start fix.
Title case with these names
In title case, brand names with non-standard capitalization stay in their canonical form, ignoring the broader title-case rules. The Story of the iPhone keeps iPhone as-is even though title case would normally apply broader rules.
Our case converter handles this through a built-in dictionary of brand names. When you convert text containing iPhone, GraphQL, PostgreSQL, etc., the brand styling is preserved regardless of the case mode you've selected. The dictionary covers 5,000+ proper nouns and brand names commonly encountered in English writing.
Specific brand styling guide

| GitHub, GitLab | PascalCase |
| Wi-Fi, USB-C, e-commerce | hyphen-separated with specific capitalization |
| Airbnb, Spotify, Netflix, Dropbox | standard PascalCase (despite their own marketing sometimes lowercase) |
When brands change their styling
Some brands change their official capitalization over time. The New York Times historically styled its own name with capitalized "The." More recent NYTimes style guides keep "The" capitalized but allow lowercase variants in some contexts.
When a brand officially changes its styling, journalism and publishing communities update gradually. Wikipedia's manual of style maintains pages on brand capitalization for many companies, updated as the brands change their own usage.
If you're writing about a brand and you're not sure how to capitalize it: check the brand's own website. The styling in their logo and marketing material is the canonical form.
The bigger picture
Brand capitalization conventions are part of a larger trend: the loosening of formal capitalization rules in English. The same forces that drove the shift from title case to sentence case in headlines are at work in brand names. Modern brands signal modernity, in part, through unconventional capitalization.
For writers, the rule is to follow the brand's lead. The brand has spent money and time on its name styling; respect it. If you're not sure how to capitalize a brand name, look up the brand's own website and copy its convention.
Our case converter handles 5,000+ brand names automatically when you paste text containing them. If you paste a paragraph mentioning iPhone, GraphQL, and Airbnb into a title-case conversion, the brand styling is preserved alongside the title-case treatment of the surrounding words.
