Liberty Mutual Ad (1st edition): "Half Acre"

Many of you asked about the origin of "pay it forward"; therefore, I checked with our good old Wikipedia and came up with this information:
Definition:

The expression "pay it forward" is used to describe the concept of asking that a good turn be repaid by having it done to others instead. More specifically, the creditor offers the debtor the option of "paying" the debt forward by lending it to a third person instead of paying it back to the original creditor. Debt and payments can be monetary or by good deeds. In sociology, this concept is called "generalized reciprocity" or "generalized exchange". A related transaction, which starts with a gift instead of a loan, is alternative giving.

History:

The concept was described by Benjamin Franklin, in a letter to Benjamin Webb dated April 22, 1784:

I do not pretend to give such a Sum; I only lend it to you. When you [...] meet with another honest Man in similar Distress, you must pay me by lending this Sum to him; enjoining him to discharge the Debt by a like operation, when he shall be able, and shall meet with another opportunity. I hope it may thus go thro' many hands, before it meets with a Knave that will stop its Progress. This is a trick of mine for doing a deal of good with a little money.

Wayne Woodrow “Woody” Hayes (February 14, 1913 –March 12, 1987) was a college football coach who is best remembered for winning five national titles and 13 Big Ten championships in 28 years at Ohio State University. He popularized the term with one of his famous quotes, "You can never pay back; but you can always pay forward."

The term "pay it forward" was coined, or at least popularized, by Robert A. Heinlein in his book, Between Planets, published in 1951:

The banker reached into the folds of his gown, pulled out a single credit note. "But eat first — a full belly steadies the judgment. Do me the honor of accepting this as our welcome to the newcomer."
His pride said no; his stomach said YES! Don took it and said, "Uh, thanks! That's awfully kind of you. I'll pay it back, first chance."
"Instead, pay it forward to some other brother who needs it."

Additional information:

In 2000, Catherine Ryan Hyde,'s novel Pay It Forward was published and adapted into a Warner Brothers film, Pay It Forward, Ryan Hyde's book and movie it is described as an obligation to do three good deeds for others in repayment of a good deed that one receives. Such good deeds should be things that the other person cannot accomplish on their own. In this way, the need to help one another can spread exponentially through society, creating a social movement with the goal of making the world a better place.

The idea of the book has been championed in real life by the Pay It Forward Foundation. The Foundation focuses on bringing the idea of paying it forward to school age children, parents, and educators. The simple idea of doing good works for others to repay the good that has happened to you is one that can easily be conveyed to children and encourages them to be socially aware and take a role in making the world a better place. The main character of the book was a 12-year-old child, thus giving other children someone they can relate to.

So ladies & gentlemen that is what I know of the phrase "pay it forward". Have you seen the television advertisement that uses this "good deed" idea in its commercial? The Liberty Mutual commercial titled "Half Acre" is effective in promoting good will! It is posted above from YouTube.
