Sorry, I haven't read any of the replies but please bear with me....Well, here is my 2 cents, I was first introduced to CB in the mid 1960's as a kid. My dad bought a tube type radio that came with a channel 11 XTAL. A rarity was a full 23 channel rig that had 46 XTALS installed, Browning was one of them)
At that time there were few people on it and you had to have a license (mine was KGN3670) you were NOT supposed to use them (according to FCC rules for idle chit-chat) and there were only 23 channels available (the police at one time used the 11 meter band but occasional skip stopped that, it was also a ham band at one time). Certain channels were to be used for calling another operator and after establishing contact you supposed to move (If I remember channel 11 was for that) the operators were very structured at that time and would use their call letters properly also, every (I believe 5 minutes) you were supposed to give your call letters. It was illegal to communicate to another station if it was 150 miles or further away).
It was monitored closely by the FCC and when people 'found' channel 22A and 22B (which was supposed to be used by businesses only (look up the frequency charts and you will understand why when the channels opened above 23, they had to move some frequency's around.
I finally bought a Penny's solid state radio and found if I removed a resistor from the xtal board it would allow me to talk on the 'business' channels. the FCC started to go around and plop down a powerful "BEEP-BEEP" signal on these channels whenever they heard us in there!
In the late 60's and early 70's there were so few people on CB you really had to scan the dial to find someone to talk to! Even though I lived near a large city, you got to know everyone on the radio (people were already not following FCC rules and we were just having fun! It was clearly stated this wasn't intended to be a HOBBY!)
When it started to become popular the FCC decided to capitalize on it and raised the prices of the license to $20 that and along with so many illegal stations as people didn't like waiting a few weeks to get their license in the mail, the FCC decided you could use part of your Social Security number as your license so you could be on-the-air as soon as you bought a radio! But we all started talking about the FFC trying to capitalize on the CB 'craze' starting to wind up we all decided to NOT buy a license and that is why we came up with "Handles", the FCC went nuts in some areas busting UN-licenced operators but by then (although the FCC won't admit it as they caused it, the 11 meter band was out of control and there was nothing they could do to return it it to what it was a decade before!
In the mid-70's the e-layer was at it's peak and this further caused the FCC problems, the laws were still in place but realizing the band was 'lost' they announced it as a license-free band!
The "Smokey and the Bandit" movies and all of Hollywood further fueled the craze and those of us that were in it from the beginning were starting to hate the foul language and the idiots that was plopping down money for a set and getting on the air! Soon, it was impossible to find a channel that wasn't crowded, most couldn't afford a sideband rig and although you could legally use it on all 23 channels nobody seemed to realize AM and SSB on the 'same' frequency didn't work, that is why the channel 16 (through word-of-mouth) became a SSB channel.
It got so crowded, those of us who still considered ourselves 'professional' started having JANS XTALS cut Xtals to go above channel 23 or a few below 1, those who tried using VFO's to do the same thing would find a pin in their coax as they would splash 3 or 4 channels in each direction!
This is a funny story, my brother and I decided we would go WAY ABOVE channel 23 for our own 'private' use and we just by chance picked 27.405 which eventually became channel 40 when the FCC expanded! I was coming home from work late one night talking to my wife on 27.405 and a guy came in and said "Break Channel 40!" I said "go-ahead, breaker" and the guy asked what kind of radio I was using as the local Lafayette Electronic store had sold this guy the very first 40-channel radio in the county!! LOL, my wife was so used to our 'private' frequency, she wouldn't come back and talk to me after the breaker left!
After that we went above and below the 40 channels again using xtal swapping and modifying our own radios, about that time, we no longer used the regular CB channels as it had become a cesspool of foul people hiding behind microphones, buying big linears and throwing dead-key, etc.
I didn't turn on a CB again till the early 80's and found it was even worse, living near Phoenix, kids seemed to have taken over certain channels like 1 and were complete jerks.
I didn't get back to turning one on again until after the Cell Phone and internet had taken over, once again I scanned the 'legal' 40 channels and thought my receive was out, finally I found a trucker on 19 and realized that CB had for the most part died.
I then decided to go up well above channel 40 (but below 10 meters) and on SSB I found some friends (most were ham radio operators that told me they came there to have fun without all the restrictions!).
What really interested me in sideband is I had my old Cobra (modified) 148 and was working on my race car late one night and threw an old base-loaded magnetic whip on top and tuned around till I found some guys just politely talking and thought they were locals, but after about an hour I heard one say "I better get to bed, I have to go into Cheyenne in the morning" So I came back and asked where they were and they said they all lived near Cheyenne, Wy! They passed me around and each said hello and they couldn't believe I was on a barefoot radio with a mag-mount antenna in a garage in PHOENIX, AZ!!!
This was the most fun I had had since my early days so now I occasionally try to make DX contacts when the solar flares cooperate!
Sorry for this long-winded post for a simple question but it gives you an idea of the life and times of a CB'er from the beginnings to now, now to answer the question: Yes, I hate to say it, but CB in my opinion is dying, now with the no-code ham license (which I passed) I think it is the final nail in the coffin, there will always be a few hanger-ons but look around your neighborhoods and see all the broken, unused CB antennas on some of the older houses.
I think it is only a matter of time before the FCC takes back the 11 meter band "for other uses".
