     李彦宏是善于借名人来事的，当然他自己也是名人了，这次这两个李姓男人之间又将演绎一出什么精彩故事呢？

     李彦宏之擅借名人可从前几年邀请前凤凰著名主持人梁冬出任市场副总裁说起，梁作为知名主持人，对媒体和广告是很有研究的，2005年来了百度之后起了很大作用，之一就是把百度在中国准确定位在了“更懂中文”，效果是显著的。但2007年初，梁冬就离开百度了，据说自己搞了个什么与公益有关的公司。

     关于李一男，褒贬不一，褒的是对于其技术能力的肯定，27岁当上了华为的副总，贬的大抵是对其为人方面，年少张狂是很容易得罪人的，不是道德品质的问题。

     李彦宏邀请李一男加盟是百度积极向全能媒体（网络＋通信）转型的标志，其意在移动互联网，这次招纳来李一男，颇有用意：

     1. 李一男在电信领域的造诣无需质疑，出任CTO在制定后续产品路标方面，对百度在技术方面很有帮助，可以补上电信一课。

     2. 李一男无论在电信领域还是资本界都有广泛的人脉及知名度，这点对百度是有益的。

     3. 百度和华为有深度技术合作，华为也在谋求通信设备之上应用领域的增值，李彦宏邀请李一男加盟不排除是经过任正非首肯之后。

     4. 李一男被媒体冠以“技术天才”，其号召力有助于招纳一批技术人才，并改观百度技术落伍的大众眼光。

 

     问题是：李一男技术出身，不擅长复杂人际关系，不知道在百度能呆多久？

三猛打法，要求士兵犹如猛虎下山，不惜一切代价打击敌人。用士气压倒敌人，用武力征服敌人，用大无畏的精神震慑敌人。唯有牺牲多壮志，敢叫日月换新天。他做到了，以至于后来所有的对手听到林彪两个字就犯憷。一个字，牛。
一点两面，就是围点打援，将十分之八九的兵力放在一点上，集中所有力量在一个拳头上。用十分之一二的兵力牵制被困之敌，集中优势敌人歼灭解围之敌。布上口袋让敌来钻，一旦上当，死死咬住，集中优势兵力像楔子一样穿插、分割、打入敌内部，打乱其建制使其顾头不能顾尾，迂回包围歼灭之。围点为虚，打援为实。布网以待，求得全歼。曾经郑洞国被围长春，东北剿总司令卫立煌眼睁睁看着郑部被困而不敢发一兵一卒。他怕什么？就林彪的围点打援。就是说，林彪完全有张飞的气势了，一夫往那一站，吼一嗓子，万夫吓得掉裤子。
四组一队即：火力组、突击组、爆破组、支援组组成一个突击队。三个人组成一个组，四个组组成一个班。这种科学分工的打法为人民军队战斗的正规化提供了样板。战争不是逞匹夫之勇，它是一门技术更是艺术，林彪四组一队的战法突破了过去传统意义上一拥而上的混乱局面，更有效更有利的打击了敌人。这也是四野以极小的代价换取东北全面解放的要领之所在。
四快一慢是指：准备要快，前进要快，扩张战果要快，追击要快，发动总攻要慢。林彪有一句名言叫：思考、判断、定决心、下命令。思考、判断要慢，他能在地图前坐上几天几夜，这就是传说中的运筹于帷幄之中。多考虑战斗中可能出现的状况，将一切问题解决于战斗之前。排除障碍以致战斗伊始就掌握主动权。稳、准、狠，战斗谋划期讲究的是稳，战斗打响了，就要直扑敌人，以最短的时间发动最猛烈的攻势，快速、准确的打击敌人，不给敌人喘息的机会，一鼓作气拿下，迅速打扫战场撤离阵地。它的精髓在于：敌明我暗，迅速出击，打完就走。始终处于不败一地。
林彪作为一个阴谋家已经魂飞湮灭、声名狼藉，但是他的战术却永垂千古，至今仍然书写于美国西点军校的教材中。

BlackBerry正在积极增加娱乐元素，向全能手机进军，但如果只是增加摄像头和蓝牙以及GPS是远远不够的，丰富的应用程序资源才是关键。

从这点上说，JAVA很有生命力，与平台无关，意味着在任何手机上都可以执行JAVA应用，同样的，意味着BlackBerry在电子邮件之外没有什么特色。

我不是专业的JAVA人士，对JAVA开发没有多深的研究，我只是觉得，跑在手机上的JAVA让我很不爽。我想可能是JAVA虚拟机/JAVA解释器的问题，那就是：目前缺乏一个在移动终端上用的高效的JAVA虚拟机。

Google Chrome提供了好的思路，鉴于JAVA在Web上的重要地位，实现JAVA加速是应用的关键，所以上面的问题变成了，如何实现在移动终端上的JAVA加速。

想起很早以前我的一篇博客，讨论了SAAS的应用能否替代运行在客户电脑上的应用软件，答案很明确，二者都在发展，而SAAS要完全替代客户端应用软件也不可能。

顺便想个问题：JAVA加速是否可以由硬件实现？这里主要指服务器端。

New Channel for Internet Companies, Content Providers and
Advertisers to Communicate Directly with Consumers
LONDON--(Business Wire)--Celltick, the pioneers of interactive idle screen mobile media,
today announced it will be expanding its product portfolio to include
a Direct to Consumer (D2C) offering. The new solution will give
Internet companies, content providers and advertisers a new channel to
reach mobile users worldwide and expand their mobile footprint.

   The solution broadcasts to Symbian and Open OS mobile phones using
point-to-point technology. Using Celltick's existing LiveScreen Media
client, content and 'teaser' messages can be streamed across millions
of mobile phone idle-screens simultaneously, creating a network of
interactive, personal billboards.

   The LiveScreen Media client has traditionally been distributed on
the SIM and has a reach capacity of over 200 million. This new
solution now offers a client that can be virally distributed via SMS
and embedded on the phone, maximising Celltick's reach. The benefit of
having the client on the phone is there is a improved user interface,
delivering a better user experience with the use of graphics and
icons.

   Internet companies and content providers can utilise this mass
reach D2C solution to communicate directly with end consumers and send
news, information, content and other rich media. The solution has
already been proven to encourage content discovery as well as
increasing downloads and WAP site traffic. It can also be used for the
delivery of highly targeted and interactive mobile advertising
campaigns, just as Celltick's traditional LiveScreen Media platform
has been doing for the last 18 months.

   Celltick's pre-launch tests of the new client have shown
remarkable results. In a pilot conducted in North America 48% of focus
group members who received the application interacted with the system
over the course of 21 days, generating a remarkable average of 10
transactions per clicker.

   The new solution will also allow Celltick's existing operator
partners to extend their offering to Symbian phones and offer a mobile
media to customers of rival networks.

   Celltick has introduced this new solution to respond to the
changing market with growing sales of Symbian and smart phones,
emerging open operating environments such as Windows Mobile and Google
Andriod, and the growth of WAP usage. Celltick intends to increase its
cooperation with Internet leaders and global media agents to support
its D2C proposition and distribute its client.

   Stephen Dunford, CEO of Celltick, said: "LiveScreen Media is the
leading idle screen marketing platform. This product extension
presents an opportunity for our partner operators and global internet
leaders to capitalize on the booming market of smart phones and open
environments. Our new solution removes the barriers to reaching the
end user with a compelling user interface which serves as a proven
platform for mobile advertising."

   About Celltick (www.celltick.com)

   Celltick Technologies Ltd., the pioneer of Active Content
Marketing, has introduced a new medium into the mobile space. Its
flagship product, LiveScreen(TM) Media, allows content providers and
advertisers to broadcast targeted content and marketing messages to
millions of mobile idle screens, turning them into a network of
interactive billboards, creating a strong revenue stream for
operators.

   Celltick cooperates with mobile operators to turn their mobile
screen into a powerful revenue driver. The company has close relations
with all network infrastructure companies, major SIM vendors, leading
handset manufacturers and industry standard organisations, as well as
global content providers and media agents.

   With a reach capacity of 200 million users, LiveScreen(TM)
Media-powered services have already proven the power of the
idle-screen as the mobile marketing channel for active content
discovery and promotion. For more than six years leading operators
worldwide have been using the platform to promote mobile content and
drive traffic to their data services. Today LiveScreen(TM)
Media-powered services generate over 35 million monthly mobile
transactions.

1. SMS

2. MMS

3. Video

4. WAP

5. Games

 

手机广告的关键是如何插入广告内容：

1. SMS

    以文本方式插入？

2. MMS

    文本或图片方式插入。由广告网关插入。

3. Video

    看视频时触发广告网关查询匹配广告视频插入视频内容前。

4. WAP

    打开网址时触发插入图片链接。

5. Games

    游戏启动前插入匹配广告。

 

目前情况下，实施有一定难度，原因在于：

1. 广告以点击计费，网络速度受限，点击响应很慢，用户体验很差。

 

2. 视频/音乐插入广告，极易引起用户反感。

 

规模应用的关键：

1. 无线网络速度提升至可流畅访问网络及下载多媒体。

 

2. 插入让用户觉得有用的广告而不会导致反感。

 

3. 手机终端进一步提升多媒体性能，可以运行flash这样的程序。

    正是Black Berry将三者紧密联系在一起，才创造了其不败的神话，至少在相当一段时间内，对手还难以真正撼动其地位，相比较而言，iPhone的A和S要素没那么有特色，有被可替代性。

 

   （以下是网上搜索到的今年初的信息：

    中移动的确在跟苹果就iPhone引入中国市场展开初步的探讨和接触，但目前仅停留在起步阶段，因为苹果的态度是想成为价值链的控制者，而且直接表示，希望从中移动获得20%或者30%的分成。苹果认为，其提供了端到端的解决方案，不仅卖手机，还卖方案，集成了内容、互联网应用，所以运营商理所当然应将收入拿出来与苹果分成。

　　对此，中移动方面“当然不同意”。高念书认为，不是中移动方面要控制这个价值链，而是中移动认为，价值链需要共同存在和发展。苹果公司在终端本身方面，有其长项，互联网功能可能很强，在Utube或者音乐互联网浏览器有着更多的体验，但通信功能很弱。换句话来说，中移动方面认为，苹果属于“传统做IT设备的公司，电信方面并不一定擅长。”）

上篇讨论了Black Berry的商业模式，那么苹果的iPhone呢？ 能否套用 App + Terminal + Service (Network)这个公式呢？

Apple iPhone的模式？

App: 娱乐应用...

   音乐，小电影，游戏，以丰富多彩的多媒体资源为主。

Terminal:

   引人入胜的iPhone 终端，这点比Black Berry强。

Service (Network):

   去网上Apple Store下音乐和电影吧...即时付费。



   Jobs一直想让中国的移动运营商引入iPhone，主要分歧在于苹果想参与利润分成，不过细想一下，要怎么个利润分成呢？ 运营商对终端进行补贴，通过签约再把补贴从用户的话费中赚回来。不知道苹果想从哪里再分些利润？

   中移动引入Black Berry是因为很Uniqe，就是很独家，没其他家能，另外移动电邮对于商务人士来讲，也是实实在在的，iPhone的功能其实其他的手机终端也能实现，国内客户对于付费下载音乐电影还没形成习惯，所以，iPhone的路在中国不好走，看来在很长一段时间里，水货商又有赚头了。

Black Berry 的模式是这样： App + Terminal + Service(Network)

App: 移动电邮服务

    正如电邮仍然是Web的最重要应用，移动电邮也将是移动Web－即手机网络服务的最重要应用之一，Black Berry提供了一种十分方便的电邮访问方式，这是成功的关键。

Terminal: 专为应用优化的终端（包括操作系统）

    终端为应用服务，最初的Black Berry终端简单而实用，尤其便于浏览和收发邮件，加上裁减合适的操作系统，除了有效的控制了终端的成本，也更突显了其最本质的特点：移动电邮。

    为吸引更多用户，新款Black Berry终端融合了部分娱乐元素，但本质不变。

Service (Network): 服务是收费的关键

   盈利模式很清晰－收取月租，为什么Black Berry不为个人用户服务？ 因为个人不会特地去安装一个Black Berry服务器。

     国外有些广告商和VoIP运营商合作，推出听/看广告免费打VoIP电话的服务，通过企业广告付费来冲抵网络成本，这个模式不新鲜，早几年就有很多类似的模式了。

    打电话前要强制听段广告？再免费我也不会用了。

    或者上Sohu/Sina看视频，最烦的是要被迫接受广告方才正常收看视频片断，我看了一次就再也不想用它们的了。

    换言之，如果品质好，服务贴心，再贵也是有市场的。

    我很理解这些媒体＋网络商的处境，广告是衣食父母，不过让用户不爽的模式，那还是省省吧。
