Thanks for pulling that item up.  The long-lines website is a cool  place.  
There are a few other sites that document the early coax and  microwave 
paths.


IIRC my past reading... some of the paths were in part military  related... 
and had some funding (and protection specs) from the federal  government.  
The AUTOVON system comes to mind.  A little googling  will bring them up.  
Reading them causes me to see 


Back to TV uses, based on the linked article's rate of $35 per month per  
airline mile, a circuit from NYC to LA cost around $86,870 a month for eight  
consecutive hours of transmission per day, and additional consecutive hours 
at  $2 per hour per month would cost $4,964 per month.


Not exactly chump change back in 1948... and not chump change today,  
either.


Had to chuckle when noting from the attached map that back in 1948, where  
I live—Marysville—was part of the coax line from Sacramento to Portland  
(wonder whether the SP railroad tracks were used?) while other parts of the  
state... notably LA to SF didn't have that luxury.


It'd be interesting to discover whether any of the old coax is still in  
place and/or in use... and what TV signals were carried at any time. North of  
here, here were (and are) CBS affiliates in Chico and Medford.

At one time, the Marysville Central office had the old "horn" type  
microwave antennas atop a tower.  


When Ma Bell and the Baby Bells were broken up (cue Neil Sedaka) the  
antennas were removed and the tower was bare for a number of years.


There's now a parabolic dish on the tower.  Can't recall where it  points.
