Nutshell

一、前言

今天開始學(xué)習(xí)互聯(lián)網(wǎng)。

學(xué)習(xí)的維度是互聯(lián)網(wǎng)和商業(yè)的關(guān)系。
潤總把這系列內(nèi)容總結(jié)為：互聯(lián)網(wǎng)世界五大基本規(guī)律。
談?wù)摦?dāng)今的商業(yè)世界，互聯(lián)網(wǎng)幾乎是避之不開的問題。
經(jīng)過多年的飛速發(fā)展，互聯(lián)網(wǎng)已然成為這個世界的基礎(chǔ)設(shè)施。
當(dāng)前、未來，一定要基于互聯(lián)網(wǎng)進(jìn)行商業(yè)思考。
我認(rèn)為，在此之前，很有必要補一下互聯(lián)網(wǎng)的歷史，于是有了這篇互聯(lián)網(wǎng)的前世今生。

二、互聯(lián)網(wǎng)的前世今生

“科技發(fā)展的過程就像建造大教堂一樣。在幾百年的歷程中，不斷有新人加入，每個人都會在現(xiàn)在的基礎(chǔ)上添加一塊磚，每個人都會說：“我建了一座大教堂。”到了下個月，又會有新磚加在之前的磚瓦上。然后來了一位歷史學(xué)家，問：“大教堂是誰建的？”彼得在這里加了幾塊石頭，保羅又多加了幾塊石頭。如果不謙虛謹(jǐn)慎的話，你就會自欺欺人地認(rèn)為自己完成的是最重要的部分。但事實是，每一項貢獻(xiàn)都必須以前人的積累為基礎(chǔ)。事物與事物之間都是環(huán)環(huán)相扣的。”

1、互聯(lián)網(wǎng)的前世今生

ARPANET阿帕網(wǎng)

NSFNET
  • 當(dāng)今的互聯(lián)網(wǎng)始于1969年阿帕網(wǎng)（Advanced Research Projects Agency Network，ARPANET）。這個基于“包交換理論”而創(chuàng)立的去中心化的分布式計算網(wǎng)絡(luò)，是由美國國防部高級研究計劃署(Advanced Research Projects Agency，ARPA)旗下信息處理技術(shù)局(Information Processing Techniques Office，IPTO)1969年底資助開發(fā)的世界上第一個計算機(jī)遠(yuǎn)距離封包交換的網(wǎng)絡(luò)。設(shè)置西海岸的四個節(jié)點：UCLA、斯坦福研究院、加州大學(xué)圣巴巴拉分校、猶他大學(xué)聯(lián)網(wǎng)構(gòu)成。
  • 在那個遙遠(yuǎn)的時代，這個粗糙的網(wǎng)絡(luò)奠定了現(xiàn)代互聯(lián)網(wǎng)的基本架構(gòu)：TELNET、FTP、網(wǎng)絡(luò)控制協(xié)議NCP以及電子郵件、網(wǎng)絡(luò)符號@等就此誕生。
  • 比起當(dāng)年阿波羅計劃的轟動效應(yīng)，阿帕網(wǎng)的偉大意義被漠視和低估。

Vox網(wǎng)站2014年用一組可視化圖片展示互聯(lián)網(wǎng)的誕生和變遷。

1.互聯(lián)網(wǎng)前身：阿帕網(wǎng)

1969年，美國國防部的高級研究計劃局(ARPA)建設(shè)了一個軍用網(wǎng)，即“阿帕網(wǎng)”(ARPANET)。這就是互聯(lián)網(wǎng)的前身。

2. 1970年：阿帕網(wǎng)擴(kuò)張

截止1970年末，阿帕網(wǎng)已發(fā)展到13個節(jié)點，包括東海岸的學(xué)校，如哈佛和麻省理工。

3. 1973年：阿帕網(wǎng)國際化發(fā)展

1973年，阿帕網(wǎng)已擴(kuò)張為40個節(jié)點，并開始國際化發(fā)展，美國的節(jié)點能能通過衛(wèi)星通信與相距較遠(yuǎn)的夏威夷州、英國的倫敦和北歐的挪威連接。

4. 1982年：阿帕網(wǎng)社區(qū)在成長

隨著阿帕網(wǎng)進(jìn)入第二個十年，它仍主要局限在美國，到1982年，該網(wǎng)絡(luò)只有大約100個節(jié)點，但這不足以支撐一個充滿活力的在線社區(qū)。

5.1984年：阿帕網(wǎng)成為互聯(lián)網(wǎng)

這張地圖顯示了阿帕網(wǎng)和CSNET的節(jié)點(標(biāo)記為“Phonenet”)。CSNET是由美國國家科學(xué)基金會資助所建立的用以提供全國范圍內(nèi)鏈接的計算機(jī)科學(xué)網(wǎng)。

6.NSFNET：第一個互聯(lián)網(wǎng)主干網(wǎng)

20世紀(jì)80年代，美國國家科學(xué)網(wǎng)絡(luò)資助美國各地建立了數(shù)個超級計算中心，并在1986年創(chuàng)建了一個直接連接這些中心的主干網(wǎng)絡(luò)，即NSFNET。此圖顯示了1992年的NSFNET，當(dāng)時，有6000個網(wǎng)絡(luò)連接到NSFNET，其中三分之一位于海外。

7. 互聯(lián)網(wǎng)成為全球性網(wǎng)絡(luò)

1993年，互聯(lián)網(wǎng)雖然仍由美國主導(dǎo)，但開始成為一個真正的全球性網(wǎng)絡(luò)。該圖顯示了一個完全交互式的超級電子論壇——新聞組(Usenet)上的信息流。

8.互聯(lián)網(wǎng)主干網(wǎng)的私有化

1994年，克林頓政府推進(jìn)了互聯(lián)網(wǎng)主干網(wǎng)的私有化。政府資助的NSFNET退役，商業(yè)公司開始介入。上面四張圖說明了世紀(jì)之交的市場演變。當(dāng)時出現(xiàn)的四家最大的私人長途網(wǎng)絡(luò)供應(yīng)商為UUNET、AT&T、Sprint和Level 3。

9.互聯(lián)網(wǎng)征服世界(2000-2012)

這張地圖顯示了從2000年到2012年全球網(wǎng)絡(luò)用戶的發(fā)展情況。互聯(lián)網(wǎng)先在富裕國家興起，然后進(jìn)入到中等收入國家，最后滲透到貧窮國家。如今，全球互聯(lián)網(wǎng)用戶超過25億，而每年還在產(chǎn)生數(shù)以億計的新用戶。

10.2012年全球有線寬帶普及率

人們有兩種登錄網(wǎng)絡(luò)的基本方法：一是通過有線寬帶，二是通過無線寬帶。由圖可見，有線網(wǎng)絡(luò)在世界各地仍然備受歡迎。

11.2012全球移動寬帶普及率

此圖顯示了全球各地的移動寬帶普及率(該圖與上張圖中同顏色的數(shù)據(jù)不能直接比較)。在發(fā)達(dá)國家，人們早期通過固定寬帶接入網(wǎng)絡(luò)，之后才擁有移動互聯(lián)網(wǎng)設(shè)備。但一些發(fā)展中國家正跳過固定寬帶網(wǎng)絡(luò)的建設(shè)階段，而這樣的方式經(jīng)濟(jì)有效，因為一個手機(jī)塔可以為數(shù)以百計的用戶提供服務(wù)。

12.2014年全球?qū)拵俣?/div>

這張圖揭示了全球各地寬帶速度，其中最快的地方是以香港為首的深綠區(qū)域，平均速度為每秒近8千萬比特。

13.面臨斷網(wǎng)風(fēng)險的國家

這張地圖顯示了各國所面對的斷網(wǎng)風(fēng)險程度。一些國家因與外界的鏈接不足而容易斷網(wǎng)。而另一些國家，如美國，有幾十條途徑連接到外部世界，使其幾乎無法采取斷網(wǎng)的審查手段。

14. 2013年全球互聯(lián)網(wǎng)自由狀況

這張地圖根據(jù)互聯(lián)網(wǎng)自由狀況，對全球各地進(jìn)行了分類。所分類型包括自由、一定程度的自由和不自由。有一些國家和地區(qū)未被評估。

三、互聯(lián)網(wǎng)的歷史

While the complete history of the Internet could easily fill a few books, this article should familiarize you with key milestones and events related to the growth and evolution of the Internet between 1969 to 2009.
1969: Arpanet


Arpanet was the first real network to run on packet switching technology (new at the time). On the October 29, 1969, computers at Stanford and UCLA connected for the first time. In effect, they were the first hosts on what would one day become the Internet.
The first message sent across the network was supposed to be “Login”, but reportedly, the link between the two colleges crashed on the letter “g”.
1969: Unix
Unix

Another major milestone during the 60’s was the inception of Unix: the operating system whose design heavily influenced that of Linux and FreeBSD (the operating systems most popular in today’s web servers/web hosting services).
1970: Arpanet network
An Arpanet network was established between Harvard, MIT, and BBN (the company that created the “interface message processor” computers used to connect to the network) in 1970.
1971: Email
Email

Email was first developed in 1971 by Ray Tomlinson, who also made the decision to use the “@” symbol to separate the user name from the computer name (which later on became the domain name).
1971: Project Gutenberg and eBooks
Project Gutenberg and eBooks

One of the most impressive developments of 1971 was the start of Project Gutenberg. Project Gutenberg, for those unfamiliar with the site, is a global effort to make books and documents in the public domain available electronically–for free–in a variety of eBook and electronic formats.
It began when Michael Hart gained access to a large block of computing time and came to the realization that the future of computers wasn’t in computing itself, but in the storage, retrieval and searching of information that, at the time, was only contained in libraries. He manually typed (no OCR at the time) the “Declaration of Independence” and launched Project Gutenberg to make information contained in books widely available in electronic form. In effect, this was the birth of the eBook.
1972: CYCLADES
France began its own Arpanet-like project in 1972, called CYCLADES. While Cyclades was eventually shut down, it didpioneer a key idea: the host computer should be responsible for data transmission rather than the network itself.
1973: The first trans-Atlantic connection and the popularity of emailing
Arpanet made its first trans-Atlantic connection in 1973, with the University College of London. During the same year,email accounted for 75% of all Arpanet network activity.
1974: The beginning of TCP/IP
The beginning of TCP/IP

1974 was a breakthrough year. A proposal was published to link Arpa-like networks together into a so-called “inter-network”, which would have no central control and would work around a transmission control protocol (which eventually became TCP/IP).
1975: The email client
With the popularity of emailing, the first modern email program was developed by John Vittal, a programmer at the University of Southern California in 1975. The biggest technological advance this program (called MSG) made was the addition of “Reply” and “Forward” functionality.
1977: The PC modem
The PC modem

1977 was a big year for the development of the Internet as we know it today. It’s the year the first PC modem, developed byDennis Hayes and Dale Heatherington, was introduced and initially sold to computer hobbyists.
1978: The Bulletin Board System (BBS)
The first bulletin board system (BBS) was developed during a blizzard in Chicago in 1978.
1978: Spam is born
1978 is also the year that brought the first unsolicited commercial email message (later known as spam), sent out to 600 California Arpanet users by Gary Thuerk.
1979: MUD – The earliest form of multiplayer games
MUD - The earliest form of multiplayer games

The precursor to World of Warcraft and Second Life was developed in 1979, and was called MUD (short for MultiUser Dungeon). MUDs were entirely text-based virtual worlds, combining elements of role-playing games, interactive, fiction, and online chat.
1979: Usenet
1979 also ushered into the scene: Usenet, created by two graduate students. Usenet was an internet-based discussion system, allowing people from around the globe to converse about the same topics by posting public messages categorized by newsgroups.
1980: ENQUIRE software
The European Organization for Nuclear Research (better known as CERN) launched ENQUIRE (written by Tim Berners-Lee), a hypertext program that allowed scientists at the particle physics lab to keep track of people, software, and projects using hypertext (hyperlinks).
1982: The first emoticon
The first emoticon

While many people credit Kevin MacKenzie with the invention of the emoticon in 1979, it was Scott Fahlman in 1982 who proposed using**
??
** after a joke, rather than the original -) proposed by MacKenzie. The modern emoticon was born.
1983: Arpanet computers switch over to TCP/IP
January 1, 1983 was the deadline for Arpanet computers to switch over to the TCP/IP protocols developed by Vinton Cerf. A few hundred computers were affected by the switch. The name server was also developed in ’83.
1984: Domain Name System (DNS)
Domain Name System (DNS)

The domain name system was created in 1984 along with the first Domain Name Servers (DNS). The domain name system was important in that it made addresses on the Internet more human-friendly compared to its numerical IP address counterparts. DNS servers allowed Internet users to type in an easy-to-remember domain name and then converted it to the IP address automatically.
1985: Virtual communities
1985 brought the development of The WELL (short for Whole Earth ‘Lectronic Link), one of the oldest virtual communities still in operation. It was developed by Stewart Brand and Larry Brilliant in February of ’85. It started out as a community of the readers and writers of the Whole Earth Review and was an open but “remarkably literate and uninhibited intellectual gathering”. Wired Magazine once called The Well “The most influential online community in the world.”
1986: Protocol wars
The so-called Protocol wars began in 1986. European countries at that time were pursuing the Open Systems Interconnection (OSI), while the United States was using the Internet/Arpanet protocol, which eventually won out.
1987: The Internet grows
By 1987, there were nearly 30,000 hosts on the Internet. The original Arpanet protocol had been limited to 1,000 hosts, but the adoption of the TCP/IP standard made larger numbers of hosts possible.
1988: IRC – Internet Relay Chat
IRC - Internet Relay Chat

Also in 1988, Internet Relay Chat (IRC) was first deployed, paving the way for real-time chat and the instant messaging programs we use today.
1988: First major malicious internet-based attack
One of the first major Internet worms was released in 1988. Referred to as “The Morris Worm”, it was written by Robert Tappan Morris and caused major interruptions across large parts of the Internet.
1989: AOL is launched
AOL is launched

When Apple pulled out of the AppleLink program in 1989, the project was renamed and America Online was born. AOL, still in existence today, later on made the Internet popular amongst the average internet users.
1989: The proposal for the World Wide Web
The Proposal for the World Wide Web

1989 also brought about the proposal for the World Wide Web, written by Tim Berners-Lee. It was originally published in the March issue of MacWorld, and then redistributed in May 1990. It was written to persuade CERN that a global hypertext system was in CERN’s best interest. It was originally called “Mesh”; the term “World Wide Web” was coined while Berners-Lee was writing the code in 1990.
1990: First commercial dial-up ISP
1990 also brought about the first commercial dial-up Internet provider, The World. The same year, Arpanet ceased to exist.
1990: World Wide Web protocols finished
The code for the World Wide Web was written by Tim Berners-Lee, based on his proposal from the year before, along with the standards for HTML, HTTP, and URLs.
1991: First web page created
First web page created

1991 brought some major innovations to the world of the Internet. The first web page was created and, much like the first email explained what email was, its purpose was to explain what the World Wide Web was.
1991: First content-based search protocol
Also in the same year, the first search protocol that examined file contents instead of just file names was launched, calledGopher.
1991: MP3 becomes a standard
Also, the MP3 file format was accepted as a standard in 1991. MP3 files, being highly compressed, later become a popular file format to share songs and entire albums via the internet.
1991: The first webcam
The first webcam

One of the more interesting developments of this era, though, was the first webcam. It was deployed at a Cambridge University computer lab, and its sole purpose was to monitor a particular coffee maker so that lab users could avoid wasted trips to an empty coffee pot.
1993: Mosaic – first graphical web browser for the general public
Mosaic - first graphical web browser for the general public

The first widely downloaded Internet browser, Mosaic, was released in 1993. While Mosaic wasn’t the first web browser, it is considered the first browser to make the Internet easily accessible to non-techies.
1993: Governments join in on the fun
In 1993, both the White House and the United Nations came online, marking the beginning of the .gov and .org domain names.
1994: Netscape Navigator
Netscape Navigator

Mosaic’s first big competitor, Netscape Navigator, was released the year following (1994).
1995: Commercialization of the internet
1995 is often considered the first year the web became commercialized. While there were commercial enterprises online prior to ’95, there were a few key developments that happened that year. First, SSL (Secure Sockets Layer) encryption was developed by Netscape, making it safer to conduct financial transactions (like credit card payments) online.
In addition, two major online businesses got their start the same year. The first sale on “Echo Bay” was made that year. Echo Bay later became eBay. Amazon.com also started in 1995, though it didn’t turn a profit for six years, until 2001.
1995: Geocities, the Vatican goes online, and JavaScript
Other major developments that year included the launch of Geocities (which officially closed down on October 26, 2009).
The Vatican also went online for the first time.
Java and JavaScript (originally called LiveScript by its creator, Brendan Eich, and deployed as part of the Netscape Navigator browser – see comments for explanation) was first introduced to the public in 1995. ActiveX was launched by Microsoft the following year.
1996: First web-based (webmail) service
First web-based (webmail) service

In 1996, HoTMaiL (the capitalized letters are an homage to HTML), the first webmail service, was launched.
1997: The term “weblog” is coined
While the first blogs had been around for a few years in one form or another, 1997 was the first year the term “weblog” was used.
1998: First new story to be broken online instead of traditional media
In 1998, the first major news story to be broken online was the Bill Clinton/Monica Lewinsky scandal (also referred to as “Monicagate” among other nicknames), which was posted on The Drudge Reportafter Newsweek killed the story.
1998: Google!
Google!

Google went live in 1998, revolutionizing the way in which people find information online.
1998: Internet-based file-sharing gets its roots
Internet-based file-sharing starts to become popular

In 1998 as well, Napster launched, opening up the gates to mainstream file-sharing of audio files over the internet.
1999: SETI@home project
1999 is the year when one of the more interesting projects ever brought online: the SETI@home project, launched. The project has created the equivalent of a giant supercomputer by harnessing the computing power of more than 3 million computers worldwide, using their processors whenever the screensaver comes on, indicating that the computer is idle. The program analyzes radio telescope data to look for signs of extraterrestrial intelligence.
2000: The bubble bursts
2000 was the year of the dotcom collapse, resulting in huge losses for legions of investors. Hundreds of companies closed, some of which had never turned a profit for their investors. The NASDAQ, which listed a large number of tech companies affected by the bubble, peaked at over 5,000, then lost 10% of its value in a single day, and finally hit bottom in October of 2002.
2001: Wikipedia is launched
Wikipedia is launched

With the dotcom collapse still going strong, Wikipedia launched in 2001, one of the websites that paved the way forcollective web content generation/social media.
2003: VoIP goes mainstream
In 2003: Skype is released to the public, giving a user-friendly interface to Voice over IP calling.
2003: MySpace becomes the most popular social network
Also in 2003, MySpace opens up its doors. It later grew to be the most popular social network at one time (though it has since been overtaken by Facebook).
2003: CAN-SPAM Act puts a lid on unsolicited emails
Another major advance in 2003 was the signing of the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003, better known as the CAN-SPAM Act.
2004: Web 2.0
Though coined in 1999 by Darcy DiNucci, the term “Web 2.0”, referring to websites and Rich Internet Applications (RIA) that are highly interactive and user-driven became popular around 2004. During the first Web 2.0 conference, John Batelle and Tim O’Reilly described the concept of “the Web as a Platform“: software applications built to take advantage of internet connectivity, moving away from the desktop (which has downsides such as operating system dependency and lack of interoperability).
2004: Social Media and Digg
The term “social media”, believed to be first used by Chris Sharpley, was coined in the same year that “Web 2.0” became a mainstream concept. Social media–sites and web applications that allow its users to create and share content and to connect with one another–started around this period. People loved the idea of being able to travel through their friends and families pictures and adventures, despite not being physically present.
Social Media and Digg

Digg, a social news site, launched on November of 2004, paving the way for sites such as Reddit, Mixx, and Yahoo! Buzz. Digg revolutionized traditional means of generating and finding web content, democratically promoting news and web links that are reviewed and voted on by a community.
2004: “The” Facebook open to college students
"The" Facebook open to college students

Facebook launched in 2004, though at the time it was only open to college students and was called “The Facebook”; later on, “The” was dropped from the name, though the URL http://www.thefacebook.com still works.
2005: YouTube – streaming video for the masses
YouTube launched in 2005, bringing free online video hosting and sharing to the masses.
2006: Twitter gets twittering
Twitter launched in 2006. It was originally going to be called twittr (inspired by Flickr); the first Twitter message was “just setting up my twttr”.
2007: Major move to place TV shows online
Major move to place TV shows online

Hulu was first launched in 2007, a joint venture between ABC, NBC, and Fox to make popular TV shows available to watch online.
2007: The iPhone and the Mobile Web
The Mobile Web

The biggest innovation of 2007 was almost certainly the iPhone, which was almost wholly responsible for renewed interest in mobile web applications and design.
2008: “Internet Election”
The first “Internet election” took place in 2008 with the U.S. Presidential election. It was the first year that national candidates took full advantage of all the Internet had to offer. Hillary Clinton jumped on board early with YouTube campaign videos. Virtually every candidate had a Facebook page or a Twitter feed, or both.
Ron Paul

Ron Paul set a new fundraising record by raising $4.3 million in a single day through online donations, and then beat his own record only weeks later by raising $4.4 million in a single day.
The 2008 elections placed the Internet squarely at the forefront of politics and campaigning, a trend that is unlikely to change any time in the near future.
2009: ICANN policy changes
2009 brought about one of the biggest changes to come to the Internet in a long time when the U.S. relaxed its control over ICANN, the official naming body of the Internet (they’re the organization in charge of registering domain names).
The Future?
Where is the future of the Internet headed? We can only assume that the Internet will continue to grow. From basic developments to things like PPC advertising, the Internet has only become more impressive over time. Share your opinions in the comments section.
