Why so many abbreviations in NOTAMs, etc.?

Why are so many things abbreviated in NOTAMs and other similar documents?
Even words that aren't very long to begin with are often abbreviated, saving
only a letter or two. I can't think of any situation today in which bandwidth
would be so severely limited that saving a letter or two would make a
difference, so I assume there is some historical reason for the abbreviations.
Were such messages transmitted by Morse code or something in the past, or is
someone still transmitting them that way (or over some other extremely slow
channel) today?

Teletype machines and abreviations understandable by everyone
without regard to native language.

Teletype machines are still used in many parts of the world.

The TTY was 45.45 bits/s in US and 50 bit/s in Europe,
with 5 bit coding (Telex).

The 8 bit 110 bit/s thingy is newer.

I was afraid of that ;-o
So it's really old then.

My first "laptop" was a portable hardcopy terminal whose standard speed
was 110 baud. High speed was 300 baud! Acoustic coupler for connectivity
and rolls of thermal paper for media. It rocked.

Yes, but back then "It rocks" refered to Granny and Pappy on the front
porch...

I was told that the fewer characters transmitted, the more
cost-effective it became.

I was hoping that in this age of the internet, they would change this
before I had to take my written (no luck). I passed it anyway, but I'm
certain that part of the questions I got wrong were for the stupid
weather reading.

Well then study up because you will be asked at your check ride.
