Personal video recorders (PVRs) let audiences create their own schedules, tailored to their mood.
Cynics might argue this is nothing new - after all, people have struggled to clear piles of videotapes lying around their living rooms for the past 25 years.
But there is something more ruthless about having a list of shows ready to go at a moment's notice.
The concept, dubbed "timeshifting", applies whether viewers record a show or if they see it on a separate "+1" service, where the entire output of a channel is shown again with a 60-minute delay, to maximise viewing opportunities.
I myself have been using Sky+ for over 3 years now and I have to say its probably something I could not live without now. It totally changes the way one views television, no longer am I dictated to by schedules, I watch what I want and when I want, and I can watch two programs that were being broadcast at the same time.
The Sky+ interface is so easy to use, its even easier then using a DVD player and its so simple to record things. I never miss my favourite programs because of the series link feature, which means all my favourite shows get automatically recorded.
Its how television should be, and with Sky removing the £10 subscription charge for Sky+ in July, it is hopefully going to become available to a LOT more people! BBC News Article
