General evolution of jukebox cabinet questions

I'm in my mid 50's, and like many of us remember jukeboxes in the 1960's and the industries cabinet designs changing from visible mechanisms to hidden ones (Which was well under way at that time).

I remember one of the fascinations with jukeboxes was the animation of loading a record, especially horizontal play jukeboxes. It was a time of the race to the moon and an invention of automation. It was cool. I remember the first time I went to a jukebox... and finding it only a box with buttons and labels and walking away because I couldn't see it work. I eventually got used to the disappointment as more and more were changed over.

Watching the mechanism work was a form of entertainment. A sort of graceful performance within itself and added to the joy of what was selected.

Can anyone tell me why the jukebox manufacturers phased out visible mechanisms? I can't believe I was the only one keeping quarters in my pocket for the disappointment. I wonder what the operators thought of the new designs... Happy about it? Indifferent? Did the move away from the animation make a difference in profit?
Even today. I think if you put a Seeburg 222 or a Rock Ola Regis 120 on one side of a room, and an enclosed jukebox with twice the capacity on the other, the higher capacity will get less coin. The chrome. The glitter. The mechanism. The sound. Am I right or am I wrong?

Was I the only one disappointed to see the evolution of cabinet designs?

The move away from visible mechanisms was a cost cutting measure. No need to chrome or paint those parts.

Thanks Ken, I suspected that was the reason.

What is puzzling however was the transition during a time which seemed to be a great competition between manufacturers. I am thinking the market perferred the glitter, chrome and animation over enclosed consoles, at least it makes sense to me. If the market wanted chrome and animation then it would naturally follow the preference of route operators for profitability.

But that apparently is not how it progressed.

Ken,
I don't think I agree with you here--
Depending on which time frame, your thinking about--Seeburg first did this with the M146 ("Trashcan") models. I ASSUME, since I was not around at the time, that this was done prior to WW II--maybe they thought that the mech was "old hat" ? But, they sure changed their minds with the introduction of the new mechanism used in the 100 A's--and all the B's on up to the LPC.
The LPC, was the MOST painted phonograph ever produced--even though the mechanism was not visible ! The idea behind the invisible mechanism then was well documented in a 1962 "flyer" they produced, headlined, "Why we won't call it a "J----B-- !"--
As I re-call this flyer, it was an attempt to get the "coin operated phonograph" into "classy locations"---
BTW--It's kind of ironic, that the last production model to come out of "the real Seeburg", had a semi visible mechanism--again ( Model SMC-1). Ron Rich
