    From the wiki I checked, CCTV was first used early in 1940s, why it was only made widely available
    only after 90s or the year of 2000?

    Was it because VHS was the only way to store video recording in those time? Was there any more
    advanced method used by governments to save the video?

    In those time, uf they used VHS, did they need to put someone sitting in the VHS machine waiting and replacing a new blank VHS
    when it's done to keep recording everything?

    Just out of curiosity
