In this presentation, Mark Davis discussed the horse racing industry and all it encompasses. I thought this to be a very an amusing topic to learn and discuss about seeing as I had little to no knowledge of it beforehand. There were many interesting facts throughout the entire presentation, pertaining to the horse racing industry for Delaware as well as then nation. We learned that the pari-mutuel wagering system in which people bet money on a specific outcome and all of the wagered money is placed into a pool to be divided amongst the winners was developed by a French man name Pierre Oller in the late 19th Century. More interesting is that the horse racing industry today has a direct economic a effect on the U.S. of $39 billion annually! I also enjoyed learning the difference of harness racing which uses a pull system compared to that of thoroughbred racing which uses a rider system. It was astonishing to hear how much money is generated in our economy through horse racing.
