Was I bragging? I was discussing a feeling I had when I was 10 years old.
I grew up with those logos, so watching that video was a pleasant nostalgia trip. But a comment up thread about being the right age did make me wonder - is the Creepy Factor here contingent on being old enough to remember watching them as a kid, but young enough that they weren’t contemporary logos when you first saw them?
My *sense *is kind of the opposite, er, if I can explain it correctly. For me, who often watched tv alone - not saying I was some orphan or anything - one moment I was watching some light, fluffy kid friendly show (though I guess, looking back, I watched all kinds of things on the seven or so channels that were available)and then the show was over and this “thing” was kind of creepy in and of itself, mostly because of the dramatic, usually loud, music but also, I guess, the way there would be a dramatic zoom or transition of the graphics. Just a total change in tone that signaled a certain finality. Off the top of my head I remember a vague sense of loneliness. And, as I mentioned, even know I get the feeling the producers of said things were going for . . .austerity (?) and that is scary to a kid (or at least this kid).So now when I see them, via this thread, of course they don’t “scare” me, but it takes me back to where I can remember how I felt at the time. I remember why, but obviously not in a way that I’m able to articulate.
The Field Communications logo scares me.
I’m with the “not exactly scary, but unsettling” contingent.
There’s something about how they pop up, totally out of context, and the abstractness of both the visuals and sound that got to me, especially late at night.
I find them almost Lovecraftian. My most unsettling nightmares aren’t about any real-life things; they’re about abstract, ominous objects with ambiguous motivations. They don’t exist in reality and thus don’t adhere to logic. They exist outside of time and space and have infinite indifference to human desire.
None of these logos makes a sound that resembles human music, even when they are created with human instruments. They remind me of the alien spacecraft in Close Encounters of the Third Kind in this respect. The visuals don’t correspond to any recognizable physics; not even a kind that is unreal but internally consistent (such as with the Road Runner cartoons). Instead we get vague, sliding forms, rotating through perhaps four dimensions and with components that appear to not fully exist in normal spacetime.
Hikon Presentation logo is also scary
I used to work in a huge millwork shop. They had a guy there whose sole job it was sweep from one end of the place to the other collecting the accumulating sawdust.
He was a big guy, probably 6’ 3", and pretty quiet. Occasionally he would rest against his broom and say “Sit Ubu sit”. He would then go back to sweeping without giving the slightest hint of why he said it.
I think this was viewed only in Canadian theatres, but when I was a kid, sitting in a dark theatre in anticipation of the upcoming film, this Famous Players logo presentation (appearing here at :56 and then again at 1:13) always freaked the hell outa me.
The way the synth builds like a scary film soundtrack, as the sections in the leaf unfurl, culminating in the “feature presentation” - creepy (and loud!)
Watching it decades later in a tiny youtube frame in my livingroom kinda dilutes what it once was, but at the time…
lol then there’s the Williams Street skull with buddies yelling.
And then Toonami comes on… “Roger that…commence broadcast countdown…” TOM gives me an orgasm
The only thing scary about most studio credits is that too many movies seem to have about six of them in a row.
Does that remind you of the riff from Who Wants to Be a Millionaire that was played just before each new question?
And how about the “Clang” that opened each location scene on *Law & Order * and its various sequels?
Ha! Finally someone who agrees with me! They should have just dubbed Super Sentai.
Stop it before I fall down laughing and hurt myself.
I remember that too, that made me piss myself…I WAS LAUGHING!
Fygar and Pooka. I should know, I’m an arcade nerd. 
That one used to always make me laugh. Every time.
I don’t think I have any fears of production logos myself. But I can see how other people might find a short video of Stephen Cannell typing, or that one that was always different persons in a fancy sombrero, irrationally horrifying.
Actually, I think I fall in the opposite category, in that I find production logos either boring or charming. MTM had some adorable ones, and I like Chuck Lorre’s.
Not a logo, but I loved the little clips at the end of The Critic.
Sir, show’s over.
But I have nowhere to go.
Ooh, here’s a remarkably weirdo topic that I care a little too much about! Well, used to care; obviously these logos haven’t been around for a long time. Whatever…opinions away!
V of Doom - Ugh. Blech. No treatise of corporate cluelessness is complete without this. You have this loud, pounding, dramatic music, and then this…this letter just gets closer and closer and closer and CLOSER…who the hell thought this was a good idea?? One of the happiest days of my life was when they switched to the “stock ticker”. I kid you not.
Paramount zoom-in - Didn’t see this often, but it kinda startled me a couple times. In retrospect, just seems like trying too hard.
Paramount blue logo - I got used to this, but it also seemed gratuitous, especially the way “Television” just zipped in out of nowhere. IIRC they had some fairly low-key shows at the time, and to have that fanfare blast at me…yeah, not too nice.
Dic - Didn’t find these too scary, but I didn’t like how they’d switch them up without warning and not give me a chance to develop some familiarity. The first time I saw that Inspector Gadget one, I nearly jumped out of my seat. (The Littles one didn’t bother me as much for some reason.)
Hannah-Barbera swirling star - Spinning object on a pitch-black background took some getting used to, but they had enough shows on that this wasn’t too hard. I think I only saw the twisting star on TV once, and I was like, “Whoa, what the heck?”
Screen Gems - I’d characterize this as more annoying than anything. That is some harsh music.
Universal - Same boat as Paramount, would be a lot more tolerable without the pretentious blowout fanfare.
Rankin-Bass - It seems benign now, but when I was younger something about it just rubbed me the wrong way. Maybe it was just the dread anticipation that something nastier would come up than a couple of circles? I dunno.
LBS, Lorimar, PBS, Ruby-Spears, Vin De Brune (sp?), Embassy, Ubu Productions - Didn’t mind these.
A few that weren’t shown:
Columbia Pictures - Never liked either one. Just grated on my ears somehow.
Stephen J. Cannell Productions - I watched the A-Team a lot, and I admit, I was dazzled the first time I saw that real-life page become an image, and then part of the logo. Pretty amazing graphics for the mid-80’s!
And I don’t remember the company, but I absolutely HATED the logo that came on at the end of Pryor’s Place. So incredibly harsh, and especially jarring given how pleasant the show generally was.
Phew, that was cathartic. All right, time to look up MTM on YouTube again! 
♪♫Take my hand…I’m a stranger in Paramount…♪♫
“Zis has been a Filmvays presentation, dahling…”
[Ozark accent] “This was a Filmways presentation!”
Yeah, Elly!
Paramount, CA 90723. 
There’s a very funny extra on the Castle Season 1 DVD in which Nathan Fillion spends a day with Stephen Cannell to learn how to act like a mystery writer. At the end, the two of them are sitting at a desk typing, Cannell on his typewriter and Fillion on a laptop. Cannell pulls the paper out of his typewriter and tosses it in the air, and just like in the production card, music plays and it turns into a “C.” Then Fillion closes his laptop and tosses it in the air, and it crashes to the floor.
