互动电视业务和传统电视业务的本质区别在于老百姓实现了“从看电视->到用电视->娱乐电视”的转变，运营商实现了“从传统单一的收视费盈利模式->复合型的立体收入模式”的转变，所以要成功实现“革命性”的突破，让老百姓养成“要用->可用->愿意用（黏住）->喜欢用（离不开）”互动电视业务的习惯，产生旺盛的人气是核心工作，随着双向互动业务项目的实施，我们和运营商即将面临的三个棘手核心问题：
1.如何打造一个可运营的成熟互动电视产品，让老百姓感到互动不再陌生，互动成为一种生活习惯……
2.如何形成良好的运作体系，能够保障互动电视业务内容的安全、高效运营……
3.如何快速发展用户，让互动电视顺利进入千家万户……
Interactive television services and conventional television services essential difference between people realized "from watching TV-> to use the TV-> Entertainment Television" changes, operators achieve a "single subscription from the traditional profit model-> complex three-dimensional revenue model "changes, so to successfully achieve the" revolutionary "breakthrough, so that people become" use-> Available-> willing to use (stick)-> like to use (inseparable) "interactive television services in the habit generate strong popularity is the core work, with two-way interactive services project implementation, we and operators will face three tough core issues:
1 How to create an interactive television operators mature product, so that people no longer feel strange interaction, interactive become a lifestyle ......
2 How to create a good operation of the system, to protect the business of interactive television content safe and efficient operation ......
