By 2015, a legitimate experience will be available to the consumer. It will probably be 1-2 more years for adoption.

I think you have to look at Internet usage to answer that question correctly as TV and Internet have different usage patterns and gratifications. I would guess 2013

That certainly depends on your definition of interactive TV. The technology certainly exists, albeit across several different devices. At this point, I think the US market is waiting for content and a distribution model. Perhaps 2012.

I don't think it's that far off. If we define VOD as an iTV application, as well as other types of 'pulled' TV content off of the internet, I'd suspect by 2015 at least 50% will be using these types of services. The real issue is that the service providers are not yet offering compelling applications, and are not advertising the interactive services that they do have that might appeal to consumers. (all advertising seems to be about cost of bundling services, instead)

2030 -- if you define ITV as anything more than VOD. For VOD, we may hit 40% by 2020.

2012

Mid-2010, but this defines iTV broadly consisting of EPG and VOD services. If you use a narrow definition of enhanced TV (iTV overlaying a video service) add two years to this date.

I would say circa 2012-2015, depending on the definition of interactivity. If we are looking at PPV or Movies on Demand, we are already there. If a TiVO model is assumed (control of shift TV) then adoption depends on the PVRs, and we should be there sooner. If a more capable interactive model is assumed, then we are looking at 2015 or beyond.

2011

2020

2050

Including all forms of ITV, I think we will hit this mark in 2010.

2011

2015

2020

All technology is 7-10 years away. After all we all have flying cars in our garages now don't we.

Within the next decade, 50% of the TV households will regularly tune in to an iTV experience. However, that experience will no longer be screen dependant. It may appear on any digital device including a Playstation, TV, iPod, PC and next generation mobile phone

If by iTV you are referring to IPTV, like HUULU.com and others, I think that threshold will be reached at the earliest in 2010, and at the latest 2012.

2014, That would include more internet connections to TV
