Nothing game show related ever frightened me, but I was scared by local station sign-offs. Not the actual sign-off message itself, or even the national anthem, but the impending color bars/tone combination or just the loud static. However, the national anthem films would send me running because I knew what was coming next. Tests of the Emergency Broadcast System were a bit nerve-wracking as well, and again that was because of the loud noise. I had no idea about the cold war/nuclear bomb implications that were originally behind the EBS.
The \"program change\" messages would usually get to me, especially coming from the then-WNEW 5 in New York, and especially when a show was cancelled/removed from the schedule, and Tom Gregory or whoever said it \"will NO LONGER be seen...\" And the Technical Difficulties slide/elevator music/announcements too...really creepy stuff!
When I was growing up, EBS tests were at 10:00 AM, just in time to interrupt the opening of The Price Is Right. (Actually, they still are at 10:00ish occasionally, but by the time it filters down from Texas Homeland Security to KEYE, it\'s usually about the time the price of the first one-bid is revealed.) I didn\'t understand that \"If this had been an actual emergency...\" was a euphemism for \"If nuclear holocaust was imminent...\" but I knew enough about the words \"actual emergency\" to know I didn\'t want to hear that noise in any other context.
The other thing along those lines was that whenever the cable company lost the signal from a station, they had an automated system that would switch to a computer system that would spell out a message about \"THIS STATION HAS CONCLUDED ITS BROADCAST DAY\" character by character, hold it for a few seconds, and then clear the screen and start again. (I assume, now, that it was configured to be able to show multiple messages if necessary, but seldom (if ever) had more than that.) Our PBS station was run on a shoestring budget at the time, so that message appeared fairly often when something broke down. It felt a little creepy to see it in the middle of the day even when I was a kid--the sense that nobody was home even though someone should be.
