The only cable companies left on copper are tiny ones. The large and mid sized ones upgraded to HFC years ago so they could offer internet, which is where they make most of their money these days - that's what funds the upgrades to the plant.
Directv to shift away from Satellite?

Still expensive to maintain..you have corrosion, bad weather and accidents..its not something you put up and forget about

Are you saying fiber networks have corrosion? How so they are glass fibers?
I will agree, right of way has to be maintained, and you will have some damage from storms, accidents, etc...
The breakdown and have issues...they wont last a 100 years like copper... the fiber core changes shape with age..lasers get weaker..issues develop..they stretch and contract..glass cracks develop

Fiber is much more susceptible to shock. So some critical comm lines had best be covered by both.
But TV isn’t critical.

Copper can last 100+ years IF it never has to be worked on ....
Once its been opened to do a repair it is then susceptible to heat and cold and weather, rain ... the company will tell you that there nothing wrong with the 100 year old cable out there ... then we tell them, TILL YOU OPEN IT.
While I was stationed on Guam, the last of the paper wrapped phone lines laid by the Japanese during the war was pulled from service.
I never said it didnt need constant maintenance but there are 100 year old copper lines still in use in places like Newark and Jersey City

Cable TV companies don't run ordinary coax around town, they only use that from the pole/street to the house. Everywhere else they aren't fiber they use "hardline" which is far more durable against damage or corrosion. It can still be broken by e.g. storms knocking trees over or a backhoe digging in the wrong place, but it is much easier to patch than fiber.
Theres over 100 year old stuff here, fortunately not alot, but theres still plenty of Lead out there.
DirecTV NOW adds DTV channel numbers back in Beta APP. This article also has some interesting details on what the owner of this site thinks AT&T is doing with their DTV servers.

Yes, but I think there's a good chance they will no longer use it after next year. If they did keep using it and thus wanted to replace it, they could probably buy a 'used' satellite already in orbit or strike a deal with Echostar to rent transponders on one of the satellites they already have at 119.
You do realize that DirecTV satellites are usually custom configured with spotbeams

Thus the reason why they pressurize the lines and use alarms to notify when the pressure is lost which would indicate a break. The pressure keeps the outside air out, humidity and anything that would degrade the copper. At times they also pump Nitrogen into the lines when there is a break until fixed which if I remember correctly is lighter than air and keeps is dry. If you live in the northeast you will see pressure caps on the lines and telephone poles which are test points. Also will hear at in some places air pumps running which keep the pressure on target etc. All for the life of copper

Thats all fine and dandy for the underground plant from the CO to the XCUT boxes ...Thus the reason why they pressurize the lines and use alarms to notify when the pressure is lost which would indicate a break.

90% of the Aerial plant is Not under Air as it has been worked on.
The spot beams on 101 & 119 will go away next year when they drop MPEG2 SD, so even if they keep 119 they will only need CONUS.
Wireless is safe
Can't tell you how many dirty copper pairs I have had to work on in my career. Glad those days are over and now deal with jitter and echo
Lots of the copper plant has been abandoned but still lives on in...... Still selling T1's too, go figure.
