When I saw KING KONG VS GODZILLA in the theater, I had no idea what I was about to see. Suddenly there were two giant monsters fighting, one that resembled a dinosaur (two, if you listen to the US Scientists!

). I was about 7, I think, and then I watched any and every movie that said Godzilla- the next two I saw on tv were GODZILLA'S REVENGE and GODZILLA VS THE SMOG MONSTER.
One of the greatest things was seeing NEW monsters- I didn't know about the Famous Monster magazine at the time (I was about ten when I bought my first one, #125 with kino on the cover) so each time I usually saw at least one new monster. Nowadays, people can't go five minutes without wanting to see a new monster. There were times I waited YEARS!
And there was no way you knew if you'd see the movie again, so you paid careful attention to it, not leaving at all, even for the commercials. It was traumatic if your alarm clock, set for 3 AM didn't go off and you missed part or all of the movie, let me tell you!
After the movies started disappearing from the airwaves, about the early 80s- you'd see them occasionally, but nearly like the 70s- and no new movies were being made- Godzilla or Gamera- you'd wonder what happened, but didn't know who to ask.
Then VHS started happening, and the Godzilla movies slowly became available, or you could trade for the ones that weren't out, and other hard to find movies like Yongary or The Magic Serpent. VHS (and now DVD) are wonderful, but there sure was something special waiting and looking and being so happy to see a Japanese monster movie in the tv guide.
