Queen Victoria wanted "television" before it had a name or even existed so that her subjects could see her address them.
Charles Francis Jenkins began work on it in the late 19th century. He called it "radiovision" because "television" traveled by wire (what we call cable television) and he couldn't afford enough high grade wire to distribute his signals to viewers.

Also, I saw some WWII era pamphlets by the US government. One was titled What Is Propaganda (with a drawing of an angry Donald Duck on the cover). Another dealt with television and possible uses for the technology after the war. The Germans maintained their television broadcasts during the 1936 Olympics on through the war. Eventually programming was geared towards officers and recuperating injured soldiers. Their technology used film which was quickly processed and broadcast all in one motion. The films remain in archives (these were different than US kinoscopes filmed OFF of a television screen).
So at least England, the US, and Germany all recognized the potential for television to be used to project the message from The State. And one of the pioneers of the technology was well aware of that aspect of it.
Barack Obama used taxpayer funds to buy messaging in fictional programs while he was president, to push an agenda on State run health care and other things.

"Trump administration will significantly scale back both of these activities, spending millions less on each program. The Affordable Care Act's advertising budget has paid for digital messaging, television ads and radio spots."
