IN 1987, a pregnant woman became ill during a mission trip to the Philippines - so ill that her doctor recommended that she have an abortion. But  she ignored him and went ahead with her pregnancy, gaving birth to her fifth child, a son, Tim.

Twenty years later, Pam Tebow's son was named the winner of college's football most prized possession, the Heisman Trophy.

The Tebow family's story will air as part of an ad with the theme of "Celebrate Family, Celebrate Life" during Sunday's Super Bowl XLIV.

Paid for by the Christian group, Focus on the Family, the acceptance of the ad by CBS marks a drastic change in policy by the major networks in accepting advocacy ads.

Just last year, NBC chose not to  air an advocacy ad sponsored by Fidelis, a Catholic group, which examined the rise of President Obama showing a child enduring hardships to become the first African American president. It featured the message: "Life: Imagine the Potential."

This week, a coalition led by the Women's Media Center, urged CBS in a letter to scrap the ad calling Focus on the Family "an anti-equality, anti-choice, homophobic organization." However, CBS officials said they examined Focus on the Family's track record, had approved the script, and found it was "appropriate for air."

In one year's time, much has changed in the pro-life movement - all for the good. From polls showing the majority of Americans are pro-life, to record crowds at the March for Life, to ads that were once turned down for prime-time events now being aired. And it's leaving those who favor abortion rights grasping at straws in their protestations of those who cherish life.
