		<description>According to a very comprehensice article in Wikipedia,http://en.wikipedia.org/wiki/Cable_television_in_the_United_States
 TV licenses were frozen from 1948-1952 which led to the creation of community antennae and cable TV. The article discusses at length the various pro and anti CATV factions and the struggle that went into its development.

The idea of a geosynchronous satellite for communication purposes was first published in 1928 by Herman PotoÄnik. The geostationary orbit was first popularised by science fiction author Arthur C. Clarke in 1945 as a useful orbit for communications satellites. As a result this is sometimes referred to as the Clarke orbit. Similarly, the Clarke Belt is the part of space approximately 35,786 km above mean sea level in the plane of the equator where near-geostationary orbits may be achieved.

As for 3D- almost definitely in 5-10 years, quality programming on the other hand...</description>

		<description>I looked it up.

Arthur C. Clarkes' paper was first published in Wireless World, October 1945, pages 305-308

(see it at http://www.lsi.usp.br/~rbianchi/clarke/ACC.ETRelaysFull.html)

Supposedly mad genius Nickoli Tesla mentioned geostationary satelites much earlier.</description>

		<description>I think the problem with the creation of a metal-glass tube was how to get a larger welded tube to safely hold a vacuum. 

In a regular vacuum tube that wasn't too much of a problem: the tube was smaller, shaped to resist a vacuum, and would likely be housed inside a radio or TV so it wouldn't pose a hazard. But a CRT is of course partly exposed, so any explosion could be dangerous. What's more, the shape of a CRT (and especially a rectangular one) doesn't afford any protection.</description>

		<description>Excellent article.

The last papragraph mentions space stations.
What year did Arthur C. Clarke publish a description of 
geostationary satelites?

AT&#38;T wouldn't pay to cable the east and west coasts together in 1949?
What year did they do it?

Oh... that  "add color to a black and white set" idea never took off because it couldn't be economically adapted to 20" and 25" sets.
It would need a huge rotating glass disk over twice the diameter of the screen.

Was there a reason metal/glass CRTs were unfeasible?
X-Rays perhaps?

Hopefully in another 60 years we'll have goggleless 3D and decent programming.</description>
