Reply to comment by Tolanator in TIL of Macadam roads. These roads were convex, raised a few inches, and made of layered crushed rock; they were state-of-the-art for the 19th century. The rise of automobiles led to the dust issues that were solved by binding the roads with tar, leading to the invention of tarmac. by jamescookenotthatone

Yeah but that's wrong isn't it? Like calling all vacuum cleaners a hoover when hoover is the brand.

Nope, neither are wrong, but for different reasons. With hoover, the brand became so dominant at one time that it's name was synonymous with the product. With tarmac, historically calling the road surface tarmac was correct and the name stuck, even though the process changed. That happens a lot with the English language, the name stays even if circumstances change. Another example is movie trailers, they were so-called because they were previews of coming attractions that were shown at the end of a film, or in other words they would "trail" a film. The name stuck even though today they are shown before a movie or even screened independently. Words endure even when meanings change.

Is using the term PC instead of Personal Computer wrong?

Abbreviation is not the same as genericization
