Business Insider, an American technology blog
male chastity cages , released the results of a survey earlier, claiming that porn sites still account for 12% of the total number of websites in the world; 28258 people watch porn sites every second; almost 40 million Americans are in the habit of browsing porn sites, and one in three of them is a woman; on average, children have been watching porn sites since the age of 11.
This result is not surprising, people living in the Internet world, have intentionally or unintentionally visited some porn sites. It is difficult for us to gain insight into the development of such sites because there is very little exact data. But what is certain is that the number of visits to porn sites will not be small. Although we are still firmly committed to "anti-pornography" and strictly prohibit logging on and browsing pornographic websites, it has not affected the popularity of pornographic websites in countries such as the United States and continue to "indecent assault" and "poison" young people.
Not long ago, dozens of websites with the top 500 unique visitors were porn, according to Google's advertising service Doubleclick. On the other hand, the data flow of porn sites is so large that it is estimated that the data transmission volume of porn sites may account for 30% of the entire Internet. According to a survey by Frank Ritchie of the New York Times, the porn industry is one of the most resilient industries, booming when the economy is booming and doubling when the economy is in recession. When a large number of websites closed in 2007, porn sites went against the tide and continued to expand, and the number soon exceeded 70,000.
Although most websites are blocked by many means, statistics show that the world's largest porn site still receives 4.4 billion visitors a month, three times the number visited by CNN's official website or the 24-hour sports network ESPN, and twice as many as the social news site Reddit. As such, from a technical point of view, porn sites must be "powerful".
However, psychologist Philip Zimbardo recently declared in a book called the decline and death of Men: why Young Men are struggling and what we can do about it: the younger generation of American men are doomed to failure. because they are affected by porn and video games. So, porn sites, we'd better stay away from it!
Naturally large scale
Judging from the 4.4 billion visits alone, porn sites are known to have to deal with huge amounts of data every day. So it
It requires a large amount of data storage, short CPU cycle, internal I / O and high-speed bandwidth, etc. The size of the website can never be small.
Let's take a look at why data traffic is so huge. The main difference between porn and non-porn sites is the length of stay of visitors. Users of some large technology sites stay between 3 and 6 minutes on average, which is enough for users to read several articles, while users of porn sites stay between 15 and 20 minutes on average. Unlike other websites whose content is mainly text and pictures, large porn sites usually push video content. Text-based popular web pages usually have millions of bytes of data, but a porn video with only 480x200 low resolution has about 100000 bytes of data per second, and a 15-minute video can consume about 90 million bytes of traffic. Multiply 90 million bytes by hundreds of millions of visitors, and it's not hard to figure out how many bytes of traffic a porn site needs to handle each month. It is conceivable that small-scale website servers may not be able to support such a huge amount of traffic.
In fact, Google's Doubleclick advertising planners underestimate the attractiveness of porn sites.
According to some first-hand data provided by a porn site that ranks "the second largest in the world", they have more porn than 100TB, with more than 100 million page views per day, which means that it transmits as much data as 950TB every day, and of course most of the data transfer is used to load videos. According to this data calculation, the monthly data processing volume of the site has 28PB, and the amount of data that needs to be processed by 100GB per second is equal to the transmission of more than 10 double-layer DVD per second.
The site also claims that its server needs to process 300000 page requests per second, and that 200 million visitors a day is not a problem. In other words, this site alone accounts for 2% of the traffic of the entire Internet. There are dozens of such porn sites, so it is no exaggeration to think that porn sites account for 30% of the data transmitted on the Internet.
The technology must be strong.
No one likes to wait in the "card machine" while watching the video. Porn websites have high requirements for all aspects of website technology, such as online payment, streaming media broadcasting, broadband popularity, credit card verification, data security and so on. So in early March 2012, when a website launched a so-called "powerful" video browser, it was teased by netizens that the so-called "powerful" feature was not new: "the players of many porn sites already have this new feature." other features are even more advanced than it. "
Some people insist after statistics that porn sites have indeed been leading the progress of Internet services.
The first is online payment. As early as the mid-1990s, porn sites have begun to practice the online payment system. According to data, the consumption of online porn in the United States in 1999 was as high as $1.3 billion, accounting for 8% of the total online consumption that year, much higher than the amount spent on buying books and air tickets online.
The second is online streaming media. Porn sites were the first to use early streaming technology that did not require any additional plug-ins. Website users have a strong demand for online streaming media broadcasting, which promotes the rapid progress of streaming media broadcasting technology. As best-selling author Lewis Perdue said: "the extreme optimization of online playback software by programmers to make paying customers enjoy sex scenes is the technical basis for today's CNN to quickly spread news videos over the Internet."
Then there is the popularity of broadband networks. Porn users' demand for high-definition pictures and videos is an important factor driving the popularity of broadband. In 2000, the New York Times reported that 20% of the broadband subscribers paid by AT&T that year were to "watch online live sex videos." in 2003, AC Nielsen Market Research also pointed out that "online music sharing and porn consumption were the two most important factors for the popularity of broadband in Europe at that time."
In addition
finger vibrator , porn sites also have many bright spots ahead of conventional websites in chat rooms, credit card verification, data security and even community operation, community atmosphere and so on. Some large porn sites also need to constantly solve many specific user problems, such as not taking risks to store resources in local bookmarks
cock cages , but also want to find them easily at any time, accurately locate and search according to their own needs, and make some of the simplest Gif dynamic pictures by themselves. Therefore
nice ass , some people say: "porn websites not only meet the original and basic needs of human beings, but also contribute to technological progress."
