A man named Rick Schwartz registered eBet.com in 1996 for $100. He held onto it for nearly 20 years — making a juicy profit off of it when the domain company Network Solutions bought it for $1.35 million.

Because Schwartz has made a number of high-profile sales (you'll run into another much later in this list), he's earned the nickname "Domain King."

"When do I sell? When the domain name is ripe," he writes on his blog. "When is it ripe? When the right buyer comes along."

Year sold: 2006

Sig Solares (the CEO of Parked.com) "wasted no time pony up the $1,500,000" when he won Cameras.com in an auction in 2006, DN Journal reported at the time.

Year sold: 2009

Today, Computer.com is a website for — you guessed it — buying computers.

Date sold: July 2013

114.com was sold privately for $2.1 million in mid-2013.

Date sold: November 2013

KK.com was sold through the Moniker/SnapNames brokerage firm for $2.4 million in late 2013.

Whisky.com was sold by Castello Cities Internet Network in a domain-only sale. Michael Castello purchased the domain 19 years ago, in March 1995, when it cost nothing to obtain.

"I had the original registration in March of 1995, and I registered it for free," Castello wrote in DN Journal. "I always liked Scotch whisky, but the real reason I registered Whisky.com was because of the Whisky a Go Go night club in Hollywood. I always enjoyed “The Whisky”, with its musical heritage and scene where the likes of The Doors and Janis Joplin played. Years later, I even offered Whisky.com to the owner’s son and he told me he didn’t need it since they already registered WhiskyaGoGo.com. That rejection would prove to be good for me."

Date sold: April 2014

Date sold: February 2015

Add an "o", and the deal gets even better.

The story of how "Domain King" Rick Schwartz flipped Porno.com is pretty incredible.

He bought it from a college kid way back in 1997, paying $42,000 even though the kid had snagged it for only $5,000 the week before.

Schwartz told The Domains that, since then, the site earned "well in excess of over $10 million via parking and redirects without every providing actual adult content." Meaning that he likely reeled in more than $20 million total from the scandalous domain.

The buyer in February's massive, all-cash sale was reportedly a company in Prague that also owns Swingers.com and PornoTv.com.

Year sold: 2007

At the time of its sale, Porn.com was the biggest all-cash transaction for a domain name and the second-largest domain sale behind Sex.com's $12 million exit. Moniker helped sell the domain to MXN Limited.

Year sold: 2008

Clek Media brokered a deal that few people believed was real: The URL was purchased by a company called Fund.com in an all-cash deal in 2008.

After the flashy sale, Fund.com ran into a lot of trouble. It had to declare most of its financials unreliable in 2009 and continuously failed to file reports. The man behind it — Jason Galanis — reportedly has an interesting history. If you go to the site now, it won't load.

Year sold: 2010

Sex.com entered the Guinness Book of World Records for the highest domain-only sale in history.

Escom LLC, which had gone bankrupt, sold it to Clover Holdings Ltd.

"It was not immediately clear what Clover Holdings plans to do with the web address," Reuters reported at the time, but we think we can probably guess...
