Television

Then:
Television was in development phases many years before ever being released. One of the biggest challenges of the television was the display. In the earliest days of television development Zworykin knew that the display needed to be better. In fact his words were "very crude images". The reason the image was so hard to see was because it used a system of mechanical mirror-drum scanners to transmit the image from the broadcast station to the television set through cathode ray tubes (CRT).

Eventually John Logie Baird came out with the first time-sharing broadcasts with the 240-line system for the BBC Television Service. Then came the 405-line Marconi-EMI system on VHF. The Marconi-EMI system became the standard for all British television broadcasts up until the 60s.

*Even in the early years of development broadcasters and television developers like RCA knew that the television system would revolutionize the way people get information. They knew that there was much more potential to get out of the television system as well. The United States eventually implemented the 525-line system in 1941 and Europe had implemented the 625-frames per second as their standard.

Following these television developments, some 20 years later, was the first initial color television. RCA came out with this NTSC television system on December 17, 1953. It quickly advanced going from a 15 inch screen to 21 inches in 1955.



Now:
The television has gone through many technological changes in the past 60 years since the first color television release. Now people are looking at HD and UHD televisions. The resolution of television has always been a main factor developers have focused on. Going from standard definition to high definition was a major leap for display in the 2000s. Standard definition which was 720 x 480 pixels was the standard resolution through the 90s. Now there is  HD resolutions of 1080p and 1080i which are 1920 x 1080 pixel resolutions as the industry standard for televisions. The resolution the only change in television systems though. Now there are different bulbs and display systems used like LCD (liquid crystal display), plasma and OLED (organic light-emitting diode). These different displays emit light differently through a series of different projections.

Another type of display being introduced is UHD (ultra high definition) this is a pixel display of 4096 x 2160 for local multiplex shows and 3840 x 2160 pixels for consumer format. This 4K resolution is going to eventually take over many systems where the current HD (1080p) televisions will become obsolete. This may be some years down the road, but will happen none the less as television is always progressing.

**I have an LCD HD TV myself and it works just fine for me. Eventually I'd like to get a 4K TV or even a smart TV would be nice to stay up to date. But with the constant progression of TV sets its hard to always get the top of the line product.



Later:
Display has been a major factor of televisions, no doubt, but television may have a change in direction in the future. More companies are working on implementing reality to video games and television. One concept that has been considered for future television is Smell-o-vision. This would essentially allow the viewer to smell different scents while watching a program or movie.

**I've actually thought about this concept before and how exactly it would work. Would someone have to buy a device to hook up to their television and with each movie they get a cartridge with scents in it and at different points in the movie the device sprays a scent? That would be pretty awesome to be able to see what an alien smells like on the move Aliens.

There are many directions television can take at this point. Companies have already come out with 3D and smart TVs which are both very successful concepts for television. But eventually they will have to come up with something new and fresh to keep with the changing times.

**I believe that is where Smell-o-vision will come in.
