At least three detailed scientific studies have attempted to determine the number of licks required to reach the Tootsie Roll center of a Tootsie Pop. A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged licks each to the center. Not to be outdone by a Big Ten rival, a chemical engineering doctorate student from the University of Michigan recorded that his customized licking machine required licks to reach the Tootsie Roll center of a Tootsie Pop.
By approximately licks. The original Tootsie Pop campaign conceived by Detroit-based Doner is a marketing moment that remains as iconic and relevant today as when it was first conceived.

We Know How Many Licks to Reach Center of a Tootsie Pop (Sort of)
The most recent answer to this question yes, there have been several—more on others later has been supplied by researchers at New York University, who were actually interested in how fluids dissolve solids under constant exposure. They used candies as their models because they knew that sugar is readily soluble in water. They had to make their own, which were more perfect, for the study.
They were invented in by an employee of The Sweets Company of America. The company changed its name to Tootsie Roll Industries in The candy made its debut in and since then various flavors have been introduced.
