Today, the Oreo cookie celebrates its 100th birthday. - 

Let me take you back exactly 100 years, to 1912.

Back then, the now debt-stricken Ireland was excited about having built the Titanic.

Here in this country, today's key super tuesday state of Ohio was carried by Theodore Roosevelt in the Republican primary.

And on March 6th, 1912, the National Biscuit Company -- Nabisco -- unveiled the Oreo Cookie.

These days, the Oreo accounts for $2 billion in annual sales.
