TV Turns 90 (axios.com)
An anonymous reader shares a report: A live webcast today will celebrate the transmission of the first electronic TV signal on Sept. 7, 1927, and the man behind it, Philo T. Farnsworth, per AP: The webcast is set for 6 p.m. ET from the original location of Farnsworth's San Francisco lab. It'll be repeated at 9 p.m. and midnight. Veteran producer Phil Savenick created the site to detail the medium's history and the contributions of Farnsworth and other TV pioneers.
There is still nothing worth watching on...

John Logie Baird in 1926 sent television images by radio.
If sending by wire instead of free space is acceptable as criteria, television was invented in the mid 19th century.
I thought John Logie Baird invented TV
imo, well worth a read. I bought the book when it first came out, and have reread it a couple of times.
The summary said "first electronic television signal". Which is accurate if you interpret it as meaning the first signal generated by electronic scanning (Baird used mechanical scanning).
I feel that the much earlier fax transmissions can be ignored; most people would consider "television" as implying a frame rate fast enough to provide an "animated" image rather than a slide show.
TV got old and senile, is boring everyone with old stories, and sometimes rehashing them thinking we won't recognise the repeat.
We haven't been using anything resembling the original technology for at least 40 years in my neck of the woods. First, there was color TV. Cable TV followed. Then we had Plasma and LCD sets. Then there was DTV. The mode of transmission and display bears no resemblance to the original. But then again, we could say the same about telephony. The work of the pioneers was still interesting.
I'm pretty sure Philo T. Farnsworth wasn't the guy who invented TV, though.

Yes, but Baird was not American, so the Americans picked someone else. Many Americans think the car was invented by Henry Ford...
The article said "electronic" television, which definitely was invented by Farnsworth. Baird was mechanically-scanned and effectively a dead-end. It's a bigger difference than between spark-gap radio and continuous-wave radio.
bullshit, the information was transmitted by electronic means. scanners and fax machines have electomechanical parts too, they aren't electronic devices?
I have to keep reminding my father that Televisions don't have any tubes in them anymore. Maybe he figures that eventually they will use carbon nanotubes, and his joke will have meaning again, but I kinda doubt it.
1984 is about a lot more than just TV. It's about a government attempting to control reality by adjusting perceptions. Examples that aren't just TV: thoughtcrime, the ministries, newspeak, Winston's job altering records and photographs to fit the narrative. The fact that we have politically correct names for these (terrorism, TLAs, memes, and "alternative facts") means some people took 1984 as a guidebook rather than a warning.
Inheritance is the sincerest form of nepotism.
As the professor would say...
The real question here is: if Philo T. Farnsworth were alive today to see what's become of television, would he be happy or sad?
I think you are wrong. Amongst the Americans who do think, I expect many of them think that Henry Ford applied mass production to cars.

That's what we were taught in school. I remember writing a paper about it in fourth grade. I think it was Daimler who had the first commercially available motorized car.

Of course Baird invented TV. That's why everyone used giant spinning discs to transmit TV pictures until CCDs came along.
Or did they use Farnsworth's video tubes?

Yes, Philo is his ancestor.

Even the electronic television predates Farnsworth. Several people had invented electronic televisons before Farnsworth. The significance behind Farnsworth is that he gave the first demonstration to the American press of a electronic television. Farnsworth wasn't the inventor of the TV or even the electronic TV.

I was going to post something like this, but I don't think over-the-air digital media is dead. Television signals, as originally created, are dead. But over-the-air digital media is very much alive.

no we really dont. his contributions to the auto industry cannot be ignored but most americans in no way believe he invented the car
have you seen my sig? there are many others like it but none that are the same
heh, I did a PPT (well some similar program at the time anyway) on the history of cars back in the mid 90s. you are close, same company as its known today but it was actually Karl Benz who created the first practical automobile in 1893

It's worth noting that Farnsworth also invented the only device to achieve Nuclear Fusion that has ever been commercially produced.

Again a completely Ameri-centric viewpoint. High definition television in Great Britain (as opposed to Baird's mechanical system) was developed by EMI in the early 30s, in parallel and independently of Farnsworth or RCA (i.e. Zworykin). The EMI developed Emitron camera (patented 1932) and 405 line-system was used to start the worlds first high definition television service by the BBC in November 1936 (to the London area).
The incandescent light bulb was developed in parallel and independently on both sides of the Atlantic. Edison in the US and Joseph Swan in the UK, with Swan patenting in the UK first.
You're confused, CRT based television is by definition electronic. Mechanical scanning referred to the use of a large spinning disk instead of a CRT.
The electron beam in the CRT in 1930s era televisions was bent (or more correctly deflected) so that it scanned the screen building up a picture, in one of two ways. Electrostatic deflection or Electromagnetic deflection.
Electromagnetic deflection uses an electro-magnet built around the outside of the electron gun. Passing a varying current through the electro-magnet varies the magnetic field produced which bends the electronic beam.
Electrostatic deflection used X-Y plates within the electron gun, a varying voltage (not current) applied to the plates attracts or deflects the electron beam.
Initially electrostatic deflection was used (in first gen TVs of 1936), these CRTs had small deflection angles meaning the tubes had to be very long (and thus mounted vertically and watched in a mirror - giving the name mirror lid televisions).
Efforts to increase the deflection angle of CRTs (and thus make shorter tubes) led to the switch to electro-magnetic deflection by 1938.
I know of those works, but anyway prefer to think of the 1920s work as "first", even though the system you mention is superior and more like what was in use until very recently with the advent of all-digital service
No we don't. Henry Ford is credited with the assembly line mass production of automobiles. Everyone knows the first car was produced by Nicolas-Joseph Cugnot, a Frenchman. Or did you mean Robert Anderson who invented the first electric car? Oh you meant GAS powered car, after BOTH of them? Seems like as dubious distinction as Henry Ford's now, doesn't it?
Baird didn't sue Farnsworth, so I have no idea what that has to do with anything.
Baird's demonstration in early 1926 is widely documented. Here's a BBC article, for example
No, but I believe his company was the first to use a moving assembly line to mass produce cars. Apparently Olds was the first to mass produce a car, with a stationary assembly line.

I hope you're right, but I am not so confident of that. These are the same people who think Europe is a country.
I knew a relative of his (also named Farnsworth) and it turns out they have the same hairstyle. Kind of a resemblance in facial features too if my memory is serving accurately.
You have it backwards, Farnsworth was the one in the 1930s who wanted the title and used courts.
I'm not confused, I know of even more television systems than those.
The point is even the electromechanical systems were coupled to radio transmission, which makes it electronic television. Just as a fax machine, scanner, copier are electronic devices.
