Maybe because no smart person does it these days.
Mr. Narendra Modi does not read while delivering a speech being the Prime Minister of India even though he carries a pile of notes in his hand. Yes, you read that right. We know Mr. Narendra Modi is a rockstar and an incredible orator but speaking in a full-fledged election rally and at the parliament are entirely different cases.
At such meetings, you got to have some essential notes handy to speak with a spot on fluency and optimism. But our Prime Minister has his own way.
Because this was difficult to recognize.
President Barack Obama uses it too.
Okay! That looks scary.
The teleprompter is firstly cleverly placed so that it cannot be seen from behind and is invisible to the audience as the screen is transparent.
Behind the scenes is the teleprompter operator controlling the speed of the scrolling text and the pace of the speaker.
So, it isn't a crime too. Smart move, Mr. Modi.
