Have you been noticing more pizza commercials than usual? It's because pizza season kicks off on Thanksgiving Eve. Pizza sales on Thanksgving Eve, according to a Market Watch report, rival those of New Year's Eve, New Year's Day and Halloween.
The idea is that families are "looking for something easy, low-priced and broadly appealing" as they're preparing their Thanksgiving meal. Another big reason is the staggered arrival time of various incoming family members.
