I’m a Canadian, so this didn’t directly involve me, but if the Americans were doing this way back when, I’ll lay odds that Canadian television had similar subliminal messages.
When I was a kid, if you stayed up late enough watching TV, you would see a short video that played the National Anthem while showing images of flags waving and various national landmarks. It always felt very creepy to watch this for some inexplicable reason. Afterward the broadcast would suddenly die, creating a lonely mess of moving black and white dots called “snow” and a loud hissing noise. On November 11, 2009, an anonymous individual uploaded a YouTube video of one of these old clips, saying, “I salvaged this reel of film from a TV station that used to sign off with it during the 1960s.” The uploader later posted a comment indicating the original reel was found in Alabama, dated 1963, and the clip was probably broadcast in several states during the 1960s. Two years after the video was first uploaded, someone discovered that it contained subliminal text, and the news quickly went viral. The words to the National Anthem are spelled out, appearing on the screen from left to right. However, as the words first materialize, a different set of words appears beneath them with the same basic font. The hidden words never appear all at once, and you need to slow the video down to a quarter of its normal speed to see the messages. The disguised text appears in approximately the same area as the words that then remain on the screen. The subliminal commands that appear in the video are as follows:
TRUST THE US GOVERNMENT
GOD IS REAL GOD IS WATCHING
BELIEVE IN GOVERNMENT GOD
REBELLION WILL NOT BE TOLERATED
OBEY CONSUME OBEY CONSUME
WORSHIP CONSUME OBEY BELIEVE
DO NOT QUESTION GOVERNMENT

(I watched the video myself, and the first word of the subliminal message in each line can be seen at regular speed, but disappears so quickly with the overlay of the words to the American national anthem that it made me doubt what I was seeing.)
Here’s a couple of photos to prove it:
