On November 12, 1998, Ma Huateng and his college classmate Zhang Zhidong officially registered and established "Shenzhen Tencent Computer Systems Co., Ltd.". The company's main business at that time was the expansion of wireless network paging systems. When the company was founded, its main business was to establish an online paging system for paging stations. 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. This is the predecessor of Tencent QQ. In February 1999, Tencent independently developed an Internet-based instant messaging network tool - Tencent Instant Messenger (TM or Tencent QQ). It has reasonable design, good ease of use, powerful functions, and stability. Efficient system operation has won the favor of users. The latest version: QQ2010Beta QQ used to imitate ICQ. ICQ is an international chat tool, which means I seek you. OICQ imitated it and added a letter O in front of ICQ, which means opening I seek you. , meaning "open ICQ", but it was accused of infringement, so the boss of Tencent changed the name of OICQ to QQ, which is the QQ we use now. Apart from the name, the logo of Tencent QQ has not changed. It has always been Little penguin. Because the little penguin in the logo is very cute, it is called cute in English. Because cute and Q are homophonic, so the little penguin is also a good name paired with QQ. By 2000, Tencent's OICQ had basically occupied more than 90% of China's online instant messaging market, and had basically secured victory. At this time, trouble began. AOL sent a lawyer's letter to Tencent. ICQ is a registered trademark of AOL, so any similar software that uses the word ICQ in its name risks infringing Chuyou's trademark rights. Request Tencent to change the name of OICQ, otherwise it will go to court. Therefore, in the OICQ2000 Build 0325 version, OICQ made another change to protect itself in advance. However, the 0325 version called itself "QQ2000" from the beginning of the installation file to avoid legal conflicts with ICQ. This QQ was originally the name of OICQ by netizens. This nickname turned out to be the official new name of OICQ overnight.
