With display monitors being rampant these days, we are force-fed with irritating public broadcasts. Our peace and quiet are brutally invaded by the advertisements in the "Road Show" on buses and between the "news broadcasts" on trains. Now they don't even leave you alone even though you are in an elevator for a minute or so. They "entertain" you with the hair-raising Cantopop music video!
That's abuse of technology at its worst!
