Question: Whom founded sixdegrees.com? Passage 1:This newer generation of social networking sites began to flourish with the emergence of SixDegrees.com in 1997, followed by Open Diary in 1998, Mixi in 1999, Makeoutclub in 2000, Hub Culture and Friendster in 2002 or Canada's first online social network Nexopia in 2003, and soon became part of the Internet mainstream. However, thanks to the nation's high Internet penetration rate, the first mass social networking site was the South Korean service, Cyworld, launched as a blog-based site in 1999 and social networking features added in 2001. It also became one of the first companies to profit from the sale of virtual goods. Friendster was followed by MySpace and LinkedIn a year later, and eventually Bebo. Friendster became very popular in the Pacific Islands. Orkut became the first popular social networking service in Brazil (although most of its very first users were from the United States) and quickly grew in popularity in India (Madhavan, 2007). Attesting to the rapid increase in social networking sites' popularity, by 2005, it was reported that Myspace was getting more page views than Google. Facebook, launched in 2004, became the largest social networking site in the world in early 2009. Facebook was first introduced as a Harvard social networking site, expanding to other universities and eventually, anyone. The term social media was introduced and soon became widespread.
 Passage 2:The band appeared on The Tonight Show with Jay Leno in 1995, performing "Camel Walk" from their album Dirt Track Date, where Jay Leno jokingly said Drew Carey performed on drums. They also appeared numerous times on Late Night with Conan O'Brien. The song "Soul City" was heard in the 1996 film Happy Gilmore, as well as the 2005 Dukes Of Hazzard movie. The song "White Trash" is featured in the soundtrack for the 1996 film Beavis and Butt-head Do America. The song "Camel Walk" is used in the 1996 movie Flirting with Disaster, the 1997 movie Perdita Durango, and the 2009 movie Schwerkraft. It also was used on the first season of the TV show Psych in the episode "Weekend Warriors." "My Baby's Got the Strangest Ways" appears on the soundtrack to the 1997 slasher film I Know What You Did Last Summer. The band can also be seen performing the song on a beach party in the movie. Four of their songs, "King of the Mountain", "Pass the Hatchet", "Cheap Motels" and "The Corn Rocket" appeared on the soundtrack to the 2001 film Super Troopers. The song "Smiley Yeah Yeah Yeah" appears on the soundtrack to the 2004 Major League Baseball video game MLB 2005. The track "40 Miles to Vegas" appeared on the EA Sports video game NASCAR 07. The song "White Trash" appears in the trailer for the 2011 movie Goon. Rick Miller appeared on episode 174 of the Americana Music Show and described their 2013 release, Dig This! as being inspired by having to dig ditches around his Kudzu Ranch recording studio to fix its septic tank. "Weird Al" Yankovic featured a style parody of Southern Culture on the Skids entitled "Lame Claim to Fame" on his 14th studio album, Mandatory Fun.
 Passage 3:As early as 500 BC, the Treveri, a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived, settled in Veldenz's fertile valley. After them, from about 50 BC to AD 500 came the Romans. Possibly about the year 1129, Gerlach I built a castle, today's Schloss Veldenz. In 1286, Rudolph of Habsburg granted Veldenz town and market rights. By 1444, the castle and its environs had passed to the Counts of Palatinate-Zweibrücken, or between 1543 and 1694 the Principality of Palatinate-Veldenz. In 1752, in Burgen near Veldenz, the widely known robber, Johann Peter Petri, also known as Schwarzer Peter (“Black Peter”), was born. From 1777 to 1797, Veldenz belonged to Bavaria. After French rule as part of Sarre department, it was annexed to Prussia in 1815. In 1835 the Veldenz Lion was adopted as the Bavarian Lion in that kingdom's coat of arms. Even today, many examples of comital building undertakings from the 18th century can be found, among them the town hall.
