Lear All About Our Directory

What Powers Our Directory?

As former directory editors, we were sad to see DMOZ announce their closure on short notice, so we decided to use their RDF file to preserve the work & create a static snapshot of their web directory.

Directory Features

Our site does not carry advertisements, but aims to reflect the historical snapshot of the DMOZ database which was located at DMOZ.org.

In addition to offering an easy-to-use drill down feature which allows users to navigate through categories, we also offer a search function to search across listings within the directory. As the site is currently configured any search can show a maximum of 100 related categories & 100 results. Where individual listings appear in search results the category associated with the listing appears under it, so users can look within the associated category for related sites.

How Expensive is this Site to Run?

It cost a few thousand dollars to build this site, but the running cost is quite low as long as we maintain a static version of the database.

If we ever allowed editorial submissions it would require shifting to a far more expensive hosting account which could cost $500 a month or more to run as the current MySQL database is over 3 gigs.

If the only review option was free then we would absorb the editorial review cost structure AOL no longer wanted, so we prefer to offer a static snapshot rather than add new listings.

We are also not convinced that a paid editorial review service would work. The Yahoo! Directory shut down in 2014 in spite of charging a recurring annual fee of $299 and being one of the earliest web directories. Further, running the site with paying customers would require spending more not only on marketing but also on a more powerful web server and a redundant hosting backup. Those costs would be in addition to hiring editors or an editorial staff to oversee volunteers.

In short, one would need to make somewhere over $5,000 per month in revenues to break even with the costs of

If one wanted to hire a programmer to help automate managing spam submissions, dealing with link rot, etc. ... that recurring upkeep of the directory would at least double the required revenues to break even.

With online advertising booming a high-traffic site can easily generate those sorts of revenues, however this site has remained fairly low traffic in spite of the great domain name & not having any ads on it, meaning the big reason search engines beat out broad-based general directories was because algorithmic search is far more scalable, more efficient, and easier for end users to use.

Do You Track Users?

Our site uses Clicky web analytics to track website traffic. We also have a Facebook like button on our pages so people can like our official Facebook page.

We do not track user search queries & if you test submitting a query to the search page we do not append the search query to the URL, so neither we nor our web analytics provider track search queries. Further, many leading search engines like Google, Bing & Yahoo! do not pass keyword referrers for most searches on their sites.

Are You DMOZ?

While this site uses the DMOZ RDF database, we are not affiliated with DMOZ.org or AOL.

Can You List My Website?

No. For the foreseeable future we plan to keep this directory as a static snapshot of sites which appeared in the DMOZ directory prior to it being shut down.

We are not adding new sites to the directory.

In the past this page listed contact information, but we stopped listing our email publicly because some inept but aggressive link builder types kept spamming us on a daily loop asking us to change links, in spite of us writing about this directory being a static snapshot.

Will You Run Our Advertisements on Your Site?

No. This site will remain ad free for the foreseeable future.

Is This Site for Sale?

No. We built this site so we could ensure the DMOZ database was preserved for many years to come.

DMOZ FAQs

What Was DMOZ?

It was a volunteer ran open directory of websites owned by AOL but maintained by volunteer editors who were topical experts who had a personal interest in the categories they edited.

When the service shut down there were 91,929 editors who managed 1,031,722 categories, listing 3,861,210 sites in 90 languages.

Who Created DMOZ?

Rich Skrenta, Bob Truel, Chris Tolles, Bryn Dole and Jeremy Wenokur.

When Was DMOZ Founded?

The service was coded & initially seeded from April to June of 1998, leveraging flat files & simple HTML forms to build the directory tree & make editing easy. It officially launched to the public on June 5, 1998.

Why Was DMOZ Created?

In March of 1998 Rich Skrenta read Danny Sullivan's report on Search Engine Watch from September 3, 1997 which highlighted slow editorial reviews & other listing problems with the Yahoo! Directory.

Listing problems were confirmed in a Chris Oakes article which Wired published on Feburary 11, 1998.

Rich Skrenta decided to create a more scalable competitor to the Yahoo! Directory based on volunteer editors.

Who Owns DMOZ?

DMOZ was acquired by Netscape in October of 1998 for $1 million.

In November of 1998 AOL acquired Netscape for $4.2 billion in stock.

Verizon announced their AOL acquisition on May 12, 2015 for $4.4 billion.

Verizon also announced they would acquire the Yahoo! operating business on July 25, 2016 for $4.83 billion. They later reduced the acquisition price by up to $350 million based on Yahoo! account credential leaks due to multiple hacks.

After the Yahoo! acquisition went through Verizon created a B2B parent brand named Oath encompassing AOL, Yahoo! and 18 other online publishing brands like TechCrunch and The Huffington Post.

After Tim Armstrong left Verizon, Verizon dumped the Oath brand name & put all these properties under the name Verizon Media Group. In December of 2018 Verizon took a $4.6 billion write down charge for goodwill on the Oath properties.

In 2021 Verizon the sold off their Yahoo! and AOL web assets to Apollo Global Management for $5 billion, retaining a 10% stake in the business.

The Yahoo IP Holdings entity still owns the DMOZ.org domain name, though Verizon shut down the associated DMOZ web directory in 2017.

When Did DMOZ Shut Down?

On February 28, 2017 AOL announced DMOZ would close down on March 14, 2017. The directory went offline & was replaced by a closed sign on March 17, 2017.

DMOZ closed.

Why Was DMOZ Shut Down?

AOL did not state a reason for closing the directory. However the directory (like other general purpose web directories) saw declining influence and usage as user search behavior shifted away from web directories to search engines. This shift was accelerated by the shift to mobile devices, as searching on mobile devices made instant answers a far better user experience than a list of websites. Many major search services like Google & Bing offer instant answers & knowledge panels in their search results which aim to answer frequently asked questions.

While searchers are still interested in a diverse range of content, online usage behavior has concentrated on a few major portal sites like Facebook, Instagram, YouTube, Amazon, eBay, Netflix, Google, Twiter, and TikTok.

The web directory model of listing websites struggled to compete on relevancy with search engines that quickly surfaced the most relevant pages (or even the most relevant answers) from widely trusted websites.

Larry Sanger claimed DMOZ was an inspiration driving the launch of Nupedia, which led to the founding of Wikipedia. Content from Wikipedia is used widely by search engines in instant answers and knowledge graph results. Search engines pay to license the content from the Wikimedia Foundation.

Online advertising has become highly consolidated with Google & Facebook taking most incremental ad revenue growth in recent years (and Amazon using their ecommerce domination to sell late funnel ads). Display ad prices have been falling for years on most sites outside of Facebook & Amazon. Facebook & Google have better user tracking & ad targeting data than most competing ad networks, in part because ISPs were prohibited from selling user data, until that regulation was overturned in the US Congress in early 2017. Facebook saw steep headwinds from Apple changing how one can use tracking information to target ads to users. The biggest & deepest ad market is the United States & over half of all cell phone users use iPhones in the U.S.

AOL's profitability has largely been driven by a couple million dial up subscribers rather than their online publishing operations. With the US Congress now allowing ISPs to use subscriber data for ad targeting some Verizon insiders believed they have a strong chance of battling the Google / Facebook duopoly in online advertising by distributing content from AOL, Yahoo! & their other online properties to their subscribers & offering more precise user ad targeting. Part of the reason Tim Armstrong left Verizon is they were more cautious with user data than he hoped & it was hard to play catch up with Google & Facebook given the ongoing declining relevance of AOL & Yahoo!.

The Verizon CEO Hans Vestberg believes the network is the core value proposition of the business and has invested aggressively in buying spectrum to build out their wireless mobile carrier business. In addition to shutting down DMOZ, Verizon has also sold off a number of other properties associated with the Yahoo! and AOL acquisitions. Buzzfeed now owns Huffington Post and the Wordpress maker Automattic now owns Tumblr. Famed value investor Warren Buffett bought a significant stake in Verizon in the fourth quarter of 2020, though sold out at a loss. Verizon kept a minority equity stake in the Yahoo!/AOL business when selling the combined entity to Apollo Global Management in 2021 for $5 billion, meaning they lost about half their intial investment on the acquisitions.

AT&T was much more aggressive with acquiring media assets than Verizon was, though AT&T took a massive bath on DirecTV (losing around $50 billion) and AT&T later merged their Time Warner holdings into a separate company tied to Discovery. Over the top streaming is a huge and growing category, though consumers may get tapped out at only wanting a couple of subscriptions. Many homes across the US have Netflix subscriptions and homes with children are likely to have Disney+ subscriptions.

Where Did The Name DMOZ Come From?

It is an acronym for Directory Mozilla. The web directory was published at directory.mozilla.com before moving to DMOZ.org.

Did DMOZ Have Any Other Names?

When the service launched it was named GnuHoo, but the Free Software Foundation's Richard Stallman objected to the use of Gnu.

The name was then changed to NewHoo, but Yahoo! objected to the use of Hoo.

Based on Yahoo!'s complaint there was a proposed name change to ZURL, but Netscape acquired the service before that name change went through.

After Netscape acquired the service they named it the Open Directory Project, then finally DMOZ.

What Made DMOZ Better Than Competing Web Directories?

Most web directories were far smaller in scope & depth. Other large directories had paid editorial staff, which made building & maintenance of the directory more expensive.

DMOZ also licensed their directory to other sites freely in exchange for a link pointing back to dmoz.org. For many years large web portals & search companies like Lycos, AltaVista & Google also ran customized versions of the DMOZ directory.

Are There Any Other Major General Web Directories?

In the early days of search DMOZ had 3 major competitors in the Yahoo! Directory, Go.com's directory & the Looksmart directory. Looksmart incorporated a volunteer directory for non-commercial results names Zeal, which they acquired in October of 2000 for $20 million.

All three leading competitors shut down prior to DMOZ's closure.

The WWW Virtual Library was created by Sir Tim Berners-Lee in 1991 & is the oldest catalogue of the web, but it is a collection of directories across academic areas rather than a single unified directory.

Best of the Web began as an award site in 1994, but later shifted to a general web directory service. It is still running, but was not as widely known & influential as the Yahoo! Directory and DMOZ once were.

Most other general web directories which still exist today are far smaller in scope / scale. The few remaining general web directories which have been online for many years typically have limited depth & consist mostly of paid placements from companies which paid for an expedited editorial review.

Vertical directories like Business.com have been sold multiple times as they have struggled to maintain relevance. Online directories associated with print yellow page books have suffered a similar fate of declining relevance. The only large directory services which still appear to be strong economically are sites which have become consumer destinations like Yelp, TripAdvisor & Zillow. These sorts of sites tend to rely heavily on user reviews, gamification, publishing custom metrics and/or freely exposing information which was previously available exclusively via paid access.

Even some of the stronger vertical review directories have struggled to maintain relevance. When TripAdvisor was spun out of Expedia in 2011 both companies had similar market caps. In October of 2024 Tripadvisor was valued at a $2.16 billion market cap while Expedia was valued at $20.53 billion. If you don't own the user transactions then as the core online networks add more features it becomes easier to get squeezed out.

The rise of small mobile devices that reinforce defaults and the spread of AI have sucked money out of many publishing business models, even as the core web tech players like Alphabet, Meta, and Amazon.com juice the ad load on their core properties.
