产品背景
Product background
2008 年 2 月 29 日，百度推出的 IM 工具，内测时期，2008 年 3 月 25 日已经获得邀请的用户可以登录使用百 度 IM。2007 年曾传出百度将推出 IM 软件，并且其名称曾有“百度小声”、“百度说吧”等名称。百度 CEO 李彦宏也曾经在自己的博客上评论说“百度小声是个不错的名字，我喜欢，就是不知道是谁的创意。”有相关人士表示，百度曾考虑过“百度小声”、“百度说吧”、“百度 Hi”等中文名字，最终带有百度空间”Hi”印记的后者在内部获得较高支持率。
On February 29, 2008, baidu launched the im tool. During the internal test period, users who have been invited on March 25, 2008 can log in to use Baidu im. In 2007, it was announced that Baidu would launch IM software, and its name used to be “Baidu whisper”, “Baidu talk bar” and other names. Baidu CEO Robin Li also commented on his blog that “Baidu whisper is a good name, I love it, but I don’t know whose creativity.” Some people said that Baidu had considered Chinese names such as “Baidu whispers”, “Baidu say it” and “Baidu Hi”, and the latter with the mark of Baidu Space “Hi” eventually gained a high internal support rate.
百度 Hi 将是打通和整合百度社区产品的通行证。用户能从百度空间页面上添加好友到百度 Hi；在贴吧、空间、知道等页面上向百度好友发起的即时通话；贴吧的吧主可建立属于该贴吧的百度 IM 群；用户可在群里向贴吧“图片库”上传图片；与百度音乐掌门人结合，可在好友列表里实时显示出好友发布的专辑；建立基于 IM 的社区聊天室。
Baidu Hi will be the pass to get through and integrate Baidu community products. Users can add friends to Baidu Hi from Baidu space page; instant call to Baidu friends from post bar, space, know and other pages; the owner of post bar can establish Baidu im belonging to the Post Bar Group; users can upload pictures to the “picture library” of the post bar in the group; combine with the leader of Baidu music, the album released by friends can be displayed in the friends list in real time; establish a community chat room based on IM.
百度对 IM 产品的定位也正是为满足其社区用户需求。百度官方网站上已经登载招聘即时通信相关人才的信息，包括即时通信客户端软件研发工程师、即时通信软件产品经理，随后所招聘的职位又悄悄增加。 据称，百度推出 IM 主要是希望把百度贴吧、百度空间、百度知道和百度百科等产品通过即时通信整合起来。 此外，百度在未来即将推出的 C2C 业务，也需要 IM 软件供买家和卖家沟通和交易使用。
Baidu’s positioning of IM products is to meet the needs of its community users. Baidu’s official website has published information on the recruitment of instant messaging related talents, including instant messaging client software R & D Engineer, instant messaging software product manager, and then the number of positions recruited has increased quietly. Allegedly, baidu launched im mainly to integrate Baidu Post Bar, baidu space, Baidu know, Baidu Encyclopedia and other products through instant communication. In addition, the C2C business Baidu will launch in the future also needs IM software for buyers and sellers to communicate and trade.
百度管理层已经明确将百度 IM 定义为公司的“战略级”产品。从产品设计，研发，测试等各个环节，全部由百度自主独立完成”。这不仅打破了以前百度可能通过收购兼并方式进入 IM 领域的传言，也证明百度至少在 1 年前就实质涉入了 IM 产品的研发工作。百度对此项目的保密工作开展程度可见一般。
Baidu management has clearly defined Baidu IM as the company’s “strategic” product. From product design, research and development, testing and other aspects, all independently completed by Baidu. “. This not only breaks the rumor that Baidu may enter the im field through acquisition and merger, but also proves that Baidu was involved in the research and development of IM products at least one year ago. Baidu’s confidentiality work on this project can be seen in general.
