eBay paid billions of dollars to gain access to Skype’s technology and user base ( more than 250 million downloads to date). However, this is only the beginning. eBay makes money from facilitating trade. eBay users pay commission for sales they make through the site, sales leads, and for promoting their services on the web site. In the (near) future, a buyer could call a seller directly from eBay’s web site, using Skype’s technology. Imagine the increase in transactions this may bring.
This is also the imperative behind Google’s GoogleTalk. Advertisers that pay for every visitor Google sends to their web site will be happy to pay even more for every client that rings them directly. Instead of the traditional model of paying per click or per sale, web sites will be able to charge advertisers for direct calls they receive from clients. PPC ( pay per click ) is dead, long live PPC ( pay per call ). Well, maybe one day.
Despite Skype’s popularity, VoIP is yet to become a mass product. Skype and similar services’ growth is hindered by several factors:
1. They require users to download and install a software on their computer;
2. They require a functioning microphone and headset/speakers;
3. The voice and service quality varies in accord with the user’s internet connection;
4. Users still differentiate between “internet calls” and normal calls, and tend to use Skype for leisure and long distance calls, while sticking to a “real” phone for business calls.
Jajah.com offers quality VoIP service at low rates with a "twist" that enables it to overcome the aforementioned hindrances. The process is simple: A user visits Jajah’s web site, enters the number he wishes to call and his own mobile or landline number. Jajah then connects the two. Hence, the web is used to initialize the call, but the actual talking takes place on a normal phone. This eliminates the need for additional software or hardware and the dependence on the user’s bandwidth. The only bandwidth necessary is to send two phone numbers through an online form. In fact, a user does not even need a computer to make a call. Mobile internet users can visit Jajah.com and make calls from their mobile to other mobiles or landlines for low rates.
The service is already available in China, and a full Chinese version of the Jajah web site is expected in the near future. Jajah is backed by technology heavyweights and it would not be surprising if its service will soon be integrated with one or two other Internet giants. Stay tuned for further developments.
Check out Jajah.com for more info and a test run.

DEMO 2006正在热身中,小容刚刚看DEMO也将在中国举行DEMO China的消息,DEMO China的网站已经建好了,这里有段文字介绍可以让大家认识一下这个会议:
DEMO China是IT创新型企业面向风险投资商、IT决策者和国际媒体发布最新革命性技术和产品、寻找风险投资、寻求业务合作的高级别活动。DEMO通过其备受信赖的专家组,每年挑选出70个具有强劲发展动力的高技术项目(例如:Palm, Skype等),推荐给风险投资家和跨国公司的技术主管,为具有创新精神的技术发展铺平道路!2006年9月,DEMO China将第一次在中国举办!在DEMO China可以和三类伙伴沟通:风险投资商,跨国公司主管和国际最著名的行业及大众媒体!
小东有写了一个“读者体验总监”的post在他的blog上,小容说:“竞争将会让市场逐渐成熟起来。”DEMO在中国的出现应证了小容这句话。DEMO给中国的会务媒体业者显示出了“专业定位,专业运作”的趋势。就像很多领域一样,拥有成熟经验的外国企业进入中国大陆市场以后,市场知识将逐渐流向本地企业,整个市场的商业运作将日趋成熟。
