Typically, an IM service will send a message to notify the user when someone on the user's call list (similar to a phonebook) is connected to IM, and the user can then start real-time communication with that person over the Internet. In addition to text, most IM services actually offer the ability to communicate via video, provided there is sufficient bandwidth. The biggest difference between real-time communication and e-mail is that there is no need to wait, no need to press "send and receive" every two minutes, as long as two people are online at the same time, like a multimedia phone, to send text, files, sound, images to each other, as long as there is a network, regardless of the other party in the end of the world, or the two sides are separated from each other by a distance.
The Internet is the only place where you can get the most out of the Internet.
The history of the Internet has always been incredibly dramatic: in 1996, four Israelis invented the ancestor of the IM - ICQ "bad boy", which was only a major online paging "In 1998, Tencent's R&D team was "excited" that QQ users exceeded 100; around 2000, the industry rumor was that Ma Huateng intended to sell QQ to Shenzhen Telecom at a price of 1 million, but Shenzhen Telecom did not want it. By 2005, Tencent had become one of China's top three Internet companies in terms of revenue, while Landmark UC, which does instant messaging as well as Tencent, relied on its second-ranked market share and number of users to be acquired by Sina in exchange for $36 million in cash and stock.
China's instant messaging history
When it comes to the history of instant messaging in China, we have to mention Ma Huateng, a mild-mannered young man who wears glasses. 1998 Tencent founder Ma Huateng was still a couch-sleeping, boxed-lunch-eating president when he was huddled in a dozens of square meters on the 4th floor of the Saige Science and Technology Park in Shenzhen, along with two other "old guards. When he and the other two "elders" crowded together in the 4th floor of Shenzhen Saige Science Park, a small workshop of a few dozen square meters of office, his business card never even dared to print the title of "general manager", but only printed the words "engineer" - Ma Huateng! The only expectation at that time was that the company would survive; he didn't realize that only five years later, he would become an overnight billionaire worth 800 million Hong Kong dollars.
Chatting has always been one of the main activities of Internet users, but at that time, the main tool for online chatting was chat rooms. The emergence of instant messaging is not like the later portrayal of the "very natural rise", from the famous paging enterprise Runcorn Ma Huateng initially did only with the paging industry related ICQ software. It was only when the telecom paging, Unicom paging, Runxun paging and other big paging companies used this kind of network pager, which gave Ma Huateng their first bucket of money, that Tencent took aim at the Internet industry, which was hot abroad. 1999, Tencent formally provided instant messaging services on the Internet.
In fact, Sina can be said to be a pioneer in this field. As early as 1999, Sina launched an IM tool called Sinapager, which was supposed to be very powerful, no less powerful than Tencent's QQ, and had a lot of users at the time. It's just that Sina wasn't so focused on IM at the time.
Once upon a time, not many people thought that instant messaging would have much of a future, because this kind of chatting tool, which needs to be online at all times, has always been constrained by the Internet's dial-up access. This has led to an increase in the number of QQ users have to constantly expand the server, Ma Huateng even can not hold out, once decided to sell QQ. Just buyers Shenzhen Telecom Data Bureau is ready to pay 600,000 yuan, and Ma Huateng insisted on selling 1 million yuan, and ultimately because the price can not reach agreement, the final negotiations ended.
But when Ma Huateng entered the Forbes China Rich List for the first time in 2003 at number 99, Tencent announced that the number of people online at the same time with QQ had reached 4.92 million, and the Internet industry began to boil over for instant messaging.
First, NetEase started to make an effort to launch a new version of its instant messaging software, NetEase Bubble 2004, in Beijing; then New Wave spent $36 million to acquire UC, which already had a huge user base, and then Sohu launched its instant messaging software, SoQ, at the beginning of 2004, and Microsoft's MSN also entered China. Microsoft's MSN has also entered China to get a foot in the door. Portal sites are clearly hoping to make a mark in this area through their longstanding user loyalty. For a while, instant messaging, along with search engines, became the hottest area of the Internet. So much so that value-added service companies are popping up to do some plug-ins on instant messaging software.
Objectively speaking, the significant increase in bandwidth investment by telecom carriers has led to a more widespread use of the Internet, which is the material basis for the boom in instant messaging; and several portals have chosen to make a push into the instant messaging market, not just to simply make up for their own mistakes, but also to promote the popularity of instant messaging.
"China's instant messaging market will undergo a sea change, of course, not that anyone can take QQ out, QQ will still occupy a large market share, but definitely not a monopoly share like now. I think this time will come soon, perhaps at the end of this year or next year." Zhou Hongyi, former president of Yahoo China, was so full of expectations.
In 2005, Ebay acquired Skype, a voice-based instant messaging software, at a cost of hundreds of millions of dollars, and at this time Skype did not achieve profitability. Before that, search engine giant Google also developed its own voice instant messaging chat tool, Google Talk, and the actions of the international giants signaled that instant messaging companies were diversifying their operations and developing in the direction of voice communications.
The same changes are happening in China, but in a different version of the story: Microsoft's MSN, when it entered China in 2004, signed up several content sites for portal expansion, while Tencent has publicly announced that it will rely on the number of users it has accumulated over the years through instant messaging to build on its foundation, and move toward portals and C2C e-commerce. Sina's UC is moving forward with value-added video services. The future of the instant messaging industry is also full of uncertainties.
Currently China's popular IM
1, Jabber
Jabber is an XML-based, cross-platform, open source, and SSL encrypted real-time communication protocol, Jabber's open architecture, so that Jabber servers around the world, no longer limited to the official. Not only that, some Jabber enthusiasts have also developed Jabber's protocol conversion program, which allows Jabber users to talk to other real-time communication program users, which is something that other well-known real-time communication software can't do!
2, IRC
IRC is InternetRelayChat abbreviation, generally speaking, he is a multi-person online real-time chat system. It is also a conversation-based system. In IRC, several people can join the same channel to discuss the same topic, such a channel, we call channel, of course, a person can join more than one channel, this is very similar to the characteristics of News. IRC was developed by JarkkoOikarinen in Finland in the late 80 (1988), the initial purpose is to allow his cloth to be used in the Internet. The purpose of IRC was to allow users of his bulletin board to not only read documents, but also to have real-time discussions online. Of course, it was fascinating, especially after IRC was used to cover the real-life Gulf War (1991), and IRC had a tendency to slowly drift apart. By now, IRC is a separate system from the bulletin boards. To date, more than 60 countries use this system.
3. ICQ
ICQ means (ISeekYou) In July 1996, four young Israelis, YairGoldfinger (26), ArikVardi (27), SefiVigiser (25), and AmnonAimr (24), were using the Internet. Feeling the inconvenience of contacting friends in real time, they founded Mirabilis in order to establish a real-time connection on the Internet. In November 1996, the first version of ICQ was released on the Internet. The first version of ICQ was published on the Internet and was immediately accepted by Internet users, who then introduced the product to each other like a sermon. Because of the surprisingly good response, it created a newly established company with the largest download rate in the history of the Internet. By May 1997, there were 850,000 users registered, and a year and a half later, there were 11.4 million users registered, of which 6 million were using ICQ, and nearly 60,000 people were registering every day. The big businessman recognized that the crowd is a business opportunity, so in June 1998, the United States know the network service company AmericanOnline (AOL) company to see this more than 10 million people, spent 400 million dollars, the acquisition of the development of ICQ Israel Mirabilis software company, this record has created another miracle in the history of network development. In September 2000, the official version of ICQ2000b was finally launched.
ICQ's shortcomings were that it didn't keep up with MSN after it appeared, such as in the inclusion of emoticons.
4. MSN
MSN is the abbreviation of Windows Live Messenger. Currently the latest Chinese version is 9.0Beta, MSN features can chat, use e-mail, transfer data... etc.
5, QQ
November 12, 1998, Ma Huateng and his college classmate Zhang Zhidong formally registered the establishment of "Shenzhen Tencent Computer Systems Co. At that time, the company's main business is to expand the wireless network paging system. When the company was founded, the main business was to establish an online paging system for paging stations, and this kind of software development project for enterprises or units can be said to be the best choice for almost all small and medium-sized network service companies.
In 1997, Ma Huateng came into contact with ICQ and became its user, he personally felt the charm of ICQ, but also saw its limitations: one is the English interface, the second is the use of the operation of the operation is quite difficult, which makes the use of ICQ in the country, although it is also relatively wide, but it is never particularly popular, mostly confined to the "netizen" level of senior hands. At the beginning, Ma Huateng and his partners thought of developing a Chinese ICQ software and then selling it to powerful enterprises, and Tencent did not think of operating a Chinese ICQ that required huge capital investment and could not earn any money because a large enterprise was interested in investing large sums of money in the Chinese ICQ field, and Tencent had also written a project construction book and had already begun the development of the design of OICQ. At the time of bidding, Tencent did not win the bidding, so Tencent decided to do OICQ by itself. It is important to know that at that time, Tencent's bidding price for OICQ was only more than 300,000 dollars. Later, when Tencent began to develop rapidly, Ma Huateng said at the right time, "We need our own Chinese network software, we need our own ICQ!", but in fact, Tencent launched OICQ is purely a coincidence, if that big business does not intend to invest money into the field of the Chinese ICQ, there will be no OICQ, if the Tencent company won the bidding, there will be no Tencent's OICQ! If Tencent had won the bid, there would have been no Tencent OICQ. Tencent's success is somehow half luck and half strength.
6. Baidu IM
On February 29, 2008, all the major technology websites published the news that the long-rumored Baidu IM software had finally begun internal testing! Baidu officials have not announced the details on their own. According to the analysis of major websites, due to the relationship between the internal testing, after the installation, you can only look at the installation directory of the file and the interface for the time being. The installation file is not big, only 5.24M, and the files in the installation directory are not much, with 58 emoticons and 28 avatars (including 6 group avatars).
Baidu Hi is an instant messaging program that combines text messaging, audio and video calls, and file transfers to make it easy to find like-minded people and connect with your friends at any time.
At the same time, news said that Baidu hi is temporarily in the internal testing stage, you can go to () on the application.
Baidu's IM will not change the instant messaging market immediately, and will not have a big impact on Tencent's QQ and MSN within a year. However, Tencent and MSN are also facing the threat of Baidu's IM development and growth in the future. And my point of view, Baidu launched IM for Baidu to enter the C2C market to make advance preparations, IM as e-commerce is one of the most effective communication tools, Baidu naturally not possible to use the products of other companies as a user communication tool. There is another reason to launch IM, which is to strengthen the stability of the Baidu community, Baidu bar user groups. The construction of the sticky user base is also the current internal testing of the "Baidu HI" instant messaging products can achieve the role of the series of products, integration of users. In this way, Baidu user groups can freely switch between Baidu space, Baidu posting, Baidu search through "Baidu HI" to complete a series of product operations, to achieve active and interactive.
