OnlyFans has tapped the founder of a lingerie company and former nude model to launch business classes on the platform.

Rachael McCrary, a longtime lingerie designer and founder of the company Spice Rack, is launching four videos on OnlyFans Wednesday. The videos are quite different from the usual OnlyFans fare. They’ll focus on pitching investors, building a brand, and navigating being an entrepreneur as a woman, McCrary tells WIRED. More videos will follow. She’s also creating a Spice Rack x OnlyFans clothing line that will launch on the site later this year.

The move is OnlyFans’ first foray into making content focused solely on building a business. It’s part of the platform’s continued push into safe-for-work content that’s meant to complement the adult content it’s known for.

“OnlyFans is a community of over 4 million creator businesses, so it makes sense that we are the perfect platform to share tips on entrepreneurship,” Keily Blair, CEO of OnlyFans, tells WIRED in a statement. “As we’ve seen in other genres like comedy and sport, it takes just one creator to recognize the opportunity and others will follow suit.”

McCrary, 48, said she met Blair at the tech conference Summit Baja last November, when they came up with the idea.

As a former SuicideGirl—a community of alt pin-up girls founded in the early 2000s—she says she felt stigmatized by her past when working in corporate fashion. At one of her jobs, she says her colleagues looked at her SuicideGirls photos while she was at work.

“I just wanted to start crying,” she says.

Then she decided to launch her own businesses, but “pitching underwear to tech VCs, I already felt like I had to prove myself more,” McCrary says. According to Inc., only 1 percent of VC-funded companies were wholly led by women in 2024. Spice Rack, which McCrary says is backed by Sequoia Partners China and Mucker Capital, is among them.

“Being naked on the internet and raising venture capital from the largest funds in the world is a very rare Venn diagram,” McCrary says, adding that OnlyFans was already looking to expand into more non-adult content. “We decided to do a masterclass format of business classes.” The first two classes will be free, while the others will require a subscription to McCrary’s page.

Over the years, McCrary says, she’s been approached by many young women, including sex workers, seeking advice on how to start their own businesses or pivot away from adult content. After she revealed her past as a SuicideGirl on a panel in 2022, she says an adult content creator came up to her and said, “I didn’t know that you were naked on the internet, and that makes me feel like I can have a career after this.”

Fifty years ago, three IBM System 370 mainframes powered a pioneering scheduling system run by the UK’s national rail operator, British Rail. Called Total Operations Processing System (Tops), when it went live on 27 October 1975, the system revolutionised the control of all rail freight operations across Britain online and in real time.

It used British Rail’s own telephone network and, along with a pair of IBM System 370/168 and a System 370/158 mainframe, Ventek minicomputers with built-in punchcard machines were installed at every area freight terminal. 

In an article published in its 30 October 1973 magazine issue, Computer Weekly described the system as: “One of the most extensive and comprehensive freight management systems in the world.”

Commenting on the 50th anniversary, Jonathan Aylen, a Tops specialist at the University of Manchester, said: “Tops covered the whole of the UK, every freight wagon and loco, every train movement and every cargo all monitored by a central computer system at Marylebone in London. The control headquarters was described as ‘space age’ for its day.” 

Marylebone housed 32 IBM 3330/33301 Control Data Drives, providing a whooping 3.2Mbytes of storage. 

The Computer Weekly article reported that Tops divided the country into 152 Tops Responsibility Areas (TRAs), each with a Ventek 9200 minicomputer system. Describing how the system operated, the Computer Weekly article noted: “The basis for Tops in the field is the punch card, one card for one wagon. As traffic is moved from one TRA to another, new cards showing the changed status are produced. The receiving officer at an Area Freight Centre (AFC) checks the cards against wagons and feeds this information into the system to update the database.”

As Aylen noted in The convergence of computing and telecommunications: Cold War to coal trains paper he co-authored in 2024, the network British Rail used was state of the art for the time, using co-axial cables for the main trunk line links, with 4Mhz analogue transmission (equivalent to 960 telephone channels). Local links were carried on 12 channel frequency division multiplex systems on balanced copper cable pairs. These gave a high-quality speech path of 4Khz channels to every major station, office complex and freight yard in the country.

But it also stretched overseas. Computer Weekly reported that Ventek minicomputers were also deployed in France at Dunkirk, and there was a Telex link in Zeebruggee, Belgium. Data from the freight centres was fed into the Marylebone computer room via a data network which spanned 400km.

“Today we take computer control of business operations for granted. But fifty years ago, it was a revolution to know what was happening right across the business in real time, especially a system which saw up to 3,000 freight train movements daily,” Aylen said. 

Tops highlighted the actual demand for wagons, which meant that many were surplus and sold for scrap, therefore reducing maintenance costs and helping to pay for the overall system.

Bob Gwynne, rail expert, said: “This had one major unforeseen consequence: one scrapyard in South Wales concentrated on quick and easy wagon disposal. Difficult steam locos were set aside for later. This breathing space led to 213 steam locomotives being acquired for preservation, approximately two-thirds of the total steam locomotives preserved today.

“So, an unintended effect of Tops was the birth of the heritage railways as a nationwide tourism product, rather than the handful of locations that pre-date 1975.”
