Tarmac was once a brand name

HERE’S THE INTERESTING PART

Just like Kleenex or Dumpster, 'Tarmac' is a victim of its own success. Short for tarmacadam, it was patented in 1901 by Edgar Hooley, who realized that mixing tar with gravel stopped roads from turning into muddy death traps. Now news anchors use it to describe every inch of an airport, much to the annoyance of pedantic civil engineers.
