Answer: Newspapers existed primarily to inform people of what was going on in the rest of the world
Explanation:
I can't really answer your question (as I don't really know enough about 18th century France), but I just want to clear up an (understandable) misconception about Feudalism in your question.
The French revolution was adamant and explicit in its abolition of 'feudalism'. However, the 'feudalism' it was talking about had nothing at all to do with medieval 'feudalism' (which, of course, never existed). What the revolutionaries had in mind, in my own understanding of it, was the legally privileged position of the aristocracy/2nd estate. This type of 'feudalism' was a creation of early modern lawyers and, as a result, is better seen as a product of the early-modern monarchical nation-state, than as a precursor to it. It has nothing to do with the pre-nation-state medieval period, or with the Crusades.
Eighteenth-century buffs, feel free to chip in if I've misrepresented anything, as this is mostly coming from my readings about the historiographical development of feudalism, not any revolutionary France expertise, so I may well have misinterpreted things.
A taping system (aka recording device) installed in the office of the President helped lead to the downfall of President Nixon. While Nixon was president, a recording device was installed in his office to record phone and in-person conversations. When being accused of having ties to the Watergate break-in, the Supreme Court ruled that Nixon must release his taped conversations. These conversations had incriminating evidence and showed Nixon's true intent as president. Ultimately, the evidence discovered by these recorded conversations lead to Nixon's resignation.
