A gTLD is any generic top-level domain — the broad category that includes .com, .org and .shop. A new gTLD is the subset delegated through ICANN's 2012 program (or a later round), such as .app, .blog and .xyz. The older, pre-2012 generics — .com, .net, .org and a handful more — are usually called legacy gTLDs.
The terms get muddled because they overlap. “gTLD” is the parent category; “new gTLD” and “legacy gTLD” are two slices of it, split by a single moment in internet history: the 2012 New gTLD Program. Before it, the generic namespace grew slowly and in small batches. After it, more than a thousand new extensions arrived in a few years. If you are new to the parent term, our primer on what a gTLD is sets the scene; this guide focuses on the old-versus-new distinction.
What are the legacy gTLDs?
The generic namespace did not start large. The original seven gTLDs date back to the 1980s:
.com · .edu · .gov · .int · .mil · .net · .org
Two later batches added a few more before the big expansion. A 2000 round introduced .aero, .biz, .coop, .info, .museum, .name and .pro. A 2004 round followed with .asia, .cat, .jobs, .mobi, .post, .tel and .travel. These pre-2012 extensions are what people mean when they say “legacy gTLD” — a small, hand-picked set, each added on its own terms.
An informal label for the generic top-level domains that existed before ICANN's 2012 New gTLD Program — the original 1980s seven plus the small 2000 and 2004 additions. Several run on older, bespoke contracts rather than the modern standardized Registry Agreement.
What changed with the 2012 new gTLD program?
The 2012 program was the first systematic, at-scale expansion of the generic namespace. Instead of approving a handful of extensions by committee, ICANN opened a structured application process that anyone with the funds and capability could enter. The numbers tell the story:
- 1,930 applications were submitted in the 2012 round.
- More than 1,200 new gTLDs were ultimately delegated into the root.
- Familiar results include
.shop,.blog,.app,.onlineand.xyz, alongside hundreds of brand extensions.
Crucially, these new gTLDs all run on ICANN's standardized base Registry Agreement — one common contract template. That uniformity is part of what defines a “new gTLD” in practice, and it contrasts with the older, individually negotiated deals behind some legacy extensions. For the mechanics of how an extension goes from application to live, see how new gTLDs are created.
Why a second round in 2026?
The 2012 program was always meant to be the first of several rounds. ICANN's 2026 round — the next major opening since 2012 — runs its application window from 30 April to 12 August 2026, with a higher fee of USD 227,000. Any extensions it produces will also be “new gTLDs.” Curious about applying? See how to register a new TLD.
Legacy gTLD vs new gTLD: how do they compare?
Side by side, the two slices differ in origin and contracts more than in how they work for you day to day:
| Legacy gTLDs | New gTLDs | |
|---|---|---|
| When introduced | 1980s, plus 2000 & 2004 rounds | 2012 program onward |
| Examples | .com .net .org .info | .shop .app .blog .xyz |
| Approx. number | ~20 | 1,200+ |
| Contract | Often older, bespoke (esp. .com) | Standardized base Registry Agreement |
| How they were added | Hand-picked, batch by batch | Open application round |
| For registrants | Familiar, broadly trusted | Descriptive, more availability |
Which should you register?
For a website you actually want people to reach, the legacy-vs-new label barely matters — both resolve everywhere and both rank the same in search. Pick the extension that best fits your name and audience: a memorable .com if it is free, or a relevant new gTLD like .shop or .design if it makes the name clearer. See how to choose a domain extension.
Do new gTLDs hurt SEO or trust?
This is the most common worry, and the short answer is no. Google has stated repeatedly that new gTLDs receive no special treatment, good or bad, in ranking — the extension is not a ranking factor. What differs is human perception: surveys still show .com enjoys the strongest instant recognition, so a new gTLD asks a little more of first-time visitors. Against that, a well-matched new extension can communicate purpose at a glance and is far more likely to be available. The practical takeaway is to weigh familiarity and price, not to fear “new” itself.
★ Key takeaways
- gTLD = any generic top-level domain; new gTLD = the 2012-program (or later) subset.
- Legacy gTLDs are the pre-2012 generics: the 1980s seven plus the 2000 and 2004 batches.
- The 2012 program drew 1,930 applications and delegated 1,200+ new extensions.
- New gTLDs use a standardized contract; some legacy ones (like
.com) use older bespoke deals. - For SEO the two are treated equally — choose on familiarity, fit and availability.
Frequently asked questions
What is the difference between a gTLD and a new gTLD?
All new gTLDs are gTLDs — the word gTLD simply means generic top-level domain. The phrase new gTLD narrows it to extensions delegated through ICANN's 2012 program or later, such as .shop and .app. Legacy gTLD is the informal term for the older ones like .com, .net and .org that existed before 2012.
What are the legacy gTLDs?
The original seven from the 1980s were .com, .edu, .gov, .int, .mil, .net and .org. A 2000 round added .aero, .biz, .coop, .info, .museum, .name and .pro; a 2004 round added .asia, .cat, .jobs, .mobi, .post, .tel and .travel.
When did new gTLDs launch?
ICANN's New gTLD Program opened applications in 2012 and began delegating extensions from 2013 onward. It was the first systematic, large-scale expansion of the namespace, receiving 1,930 applications and delivering more than 1,200 new gTLDs such as .shop, .blog, .online and .xyz.
How many new gTLDs are there?
More than 1,200 new gTLDs have been delegated since 2012. Together with the legacy generic extensions and around 300 country-code TLDs, that brings the total number of TLDs in the IANA root to roughly 1,500 or more.
Are new gTLDs worse than .com for SEO or trust?
Search engines treat new gTLDs the same as legacy ones — the extension itself is not a ranking signal. The real differences are familiarity and price. Visitors still recognize .com most readily, while a relevant new gTLD like .shop or .app can make a name clearer and is often available when the .com is taken. See do TLDs affect SEO.
Do legacy and new gTLDs run on different contracts?
Largely, yes. New gTLDs operate under ICANN's standardized base Registry Agreement introduced for the 2012 program. Several legacy gTLDs, especially .com, run on older bespoke contracts that pre-date that standard, which is one reason their pricing and rules can differ.
