Some say Michelle Obama's electrifying speech in Philadelphia will go down in history. 

But what does it take to deliver a speech of that magnitude?

Roaring crowds ushered in First Lady Michelle Obama to the podium, long before she delivered the night’s big speech.

“Because of Hillary Clinton my daughters and all our sons and daughters now take for granted that a woman can be president of the United States,” she said to thunderous applause.

Mrs. Obama’s skill is more than just about reading off a teleprompter. According to a local public speaking expert, Michelle Obama was able to capitalize on a crowd that viewed her favorably and use the proper cadence, inflection and body language to captivate the crowd.

“Using animation to inspire, motivate and propel because the data is not inspiring,” says Guy Monroe, the self-proclaimed Charisma Coach.

The First Lady was tasked with connecting to the nearly 25.7 million viewers watching at home on top of the thousands of delegates in the arena.

However, keeping up with the way we connect to our leaders proved challenging at the onset of television.

In 1960, the first televised presidential debate between Senator John F. Kennedy and Vice President Nixon, saw a nervous Nixon unravel before the American public.

“So we see the concern in his eyes and anxiety.  I see a man who’s not at easy, you see? It can be interpreted as not capable,” says Monroe.

Addressing the American public would become an art form. Two decades later, President Ronald Reagan displayed his calm but assertive demeanor in front of the camera. His “shining city on a hill” speech immortalized him in the eyes of America.

“Let me offer lesson number one about America, all great change in America begins at the dinner table,” Reagan told Americans in his farewell address.

Data from Nielsen shows 23 million Americans tuned in on the first night of the Republican National Convention in Cleveland.

Almost 3 million more tuned in for the Democrats' first night in Philadelphia.
