“In many countries the press is censored every day” reads the standard looking highlighter from IGFM. Most people wouldn’t take a second glance at the little yellow stick with censorship information printed on it. After all, promotional pens and highlighters are in no short supply at press conferences.
This particular organization decided to come up with something that would really grab attention. So they replaced the yellow ink with black, then they handed out the highlighters with no prior explanation.
During the conference when a member of the press tried to highlight a sentence in their notes a thick, black censorship line appeared rather than the bright, cheery yellow one that would be expected.
That drilled the point home. Reporters all over the world are censored every day, and it’s a lot worse than a silly black line in your notes.
