For the past decades television and technology executives in the US. Have been promings that views would use their remote controls for something other than channel surfing. Well. We’ve seen how that’s turned out. Ventures like Microsoft’s WebTV flopped. In Britain,however,that drem has become a reality .Thirty-one percent of Britain’s 26 million households have interactive TV ， compared with only 8% in the US. _{<seA
How did Britain, a coutry not known for its high-tech powers ,achieve such dominance in interative television? Because cable was novelty in England until recently, the country was able to skip a generation of technology and go straight to digital TV , while US cable companies still upgrading their networks .Consumer behavior differs too .Fewer Britons own PCs ,and those who have internert access spend less time online than Americans, making them more willing to utilize Web-like functions on their TV sets. %D$]V SP;
