Television has changed over the years, moving from black & white TVs, to color TVs moving onto SD TVs and now HD Television. HDTV are more popular than any other kind of TV because of their superior picture quality and the ability to implement multiple technologies such as internet widgets, personal video recording capabilities and enhanced features more than previous versions of TV.
HD Television has its roots dating back to the early 1940s when it was first tested in Europe. It was however only implemented in the last 1950s. It did become common place as analogue TVs became more popular worldwide. In the 1990s, the digital TV platform began to be adopted as the replacement for analogue TV and many manufacturers began to manufacture HD TVs for the new platform. However because of some irregularities towards the turn of the millennium, there was some confusion on the benefits of HD TVs and how they could give consumers all their marketed benefits.
Many consumers have bought HD TVs labelled HD Ready that at the time of their manufacturing were considered ready for HD but with some significant changes that occurred in regards to the proprietary technology that would be used in HD television (such as Blu-Ray, Progressive scanning and others), HD TVs changed in their format and some consumers found that their HD TVs were not future proof.
However since the bulk of digital standards that have been adopted for HD Televisions may not be fully implemented until at least 2012, there is some hope.
HD TVs allow for consumers to enjoy not only sharper more clear imagery but also better viewing ranges. With some of the original SD TVs, the rule of thumb for viewing distance was between 3 to 6 times the screen size in inches. When HD TV was introduced the resolution was much sharper and clearer making it easy to sit closer and not notice any image pixilation. Thus the rule of thumb of viewing distance for HD TVs is 1.5 to 3 times the screen size in inches.
Getting the full HD TV experience is at the top of a lot of consumers list and there are many accessories and accompanying electronics that can ensure a worthwhile viewing experience. With SD TV, consumers joked at how they could see the world from the couch, now with HD Televisions, the world seems to have been brought even closer. As a replacement to SD TV, HD TV will do well once its benefits and full features are realized around the world.
