telegraph. It could transfer an image through wires, similar to the way telephone wires transfer sound.

experimented with selenium. It helped them figure out that they could transform pictures into signals to be sent over wires more easily.

Photo phone

• 1880• Alexander Graham Bell and Thomas Edison

came up with the Photo phone. It could transfer sound, but they aimed for it to do the same with pictures at a higher quality.

Far Sight

•January 1,1900 •Russian scientist Constantin Perskyi coins the word “television” at the world’s fair in Paris. Inventors in the U.S., Europe and Japan work on various devices to transmit images.

Early Television

• January 1, 1926• Scottish engineer John Baird develops the Televisor,

essentially a radio device with a neon tube and spinning metal disk that projects and magnifies a stamp-sized image.

Television is tested publically

TV broadcasts – broadcasts are now internationally relayed.

Mankind’s First Step

Digital Satellite Dishes

• 15th Jan, 1996 Digital Satellite Dishes In mid-January, digital satellite dishes are released. They became the biggest selling electronic item in history, next to the VCR.

Projection

since color television, high-definition TV became available as a result of the global transition from analog television broadcasting to digital TV. Digital TV arrived in the United States in late 1998. The first HDTV broadcast in Canada was Super Bowl XXXIV in January, 2000.

TiVo, PVR,DVR

• 1999• Digital video recorders were introduced at the

1999 Consumer Electronics Show (CES), allowing viewers to simultaneously record one TV show while watching another.

Plasma and LCD

• 1999• At the 1989 Winter Consumer Electronics

Show, Sharp Electronics introduced a 14-inch liquid crystal display television billed as “the world's largest color liquid crystal display.”

3D TV

• 2010• Hyped at the 2010 CES, the 3D-at-home

revolution fizzled when consumers failed in any great numbers to snap up the expensive units with their silly glasses and less than abundant content. Still, shipments of 3D LCD TV panels rose to 21.2 million in 2011, or 10 per cent of all LCD TV panels shipped.

To the Future!!!!!

Eye and Voice Control

The future of television could be more accessible and easy to use for people with disabilities. (Or

people who are really lazy) It could be controlled with your eyes or by speaking and would enable

you to watch TV without moving.

feel like you’re actually in the show! Holograms can produce a 3d figure of your favorite superstar right in your own home!

Predictions

• You’ll be able to choose to buy or stream any particular show or channel or brand. Ads — tailored just to what might interest you — will be delivered to you as product placements or surrounding your favorite shows and events.

Water Television

• Uses a humidifier to create a curtain of air made out of tiny water particles that feels dry to the touch, but is substantial enough to project an image on to. It's even interactive - built-in cameras and software algorithms analyze your hand movements so that you can manipulate the image.

See-Through TV

• Samsung's Transparent Showcase is a glass box big enough to contain a product that lets retailers float video promotions over the front panel.

• Then at the end of the day, when unplugged, the glass turns black.

• It hints at a time when TVs might be used as augmented reality devices, providing information about objects placed behind them.

Google Glass

Google Glass is a wearable computer which allows you to control it with your voice alone. It also has a touch

panel along the side for control. Google Glass can connect to Facebook, Twitter, and other social

networking sites.
