Revenue from Pennsylvania casinos dropped by nearly $800 million last year compared to 2019 as the COVID-19 pandemic ravaged the industry with forced closures and reduced capacities. And at least one industry expert said the casino business will not soon return to pre-coronavirus levels and those that think otherwise are “crazy.” The Pennsylvania Gaming Control Board reported last month that the state’s 13 casinos generated $2.6 billion in 2020, down about 22% from 2019 when it totaled $3.4 billion, after they were closed a third of their usual operating days due to the pandemic. The figures include combined revenue from slots, table games, sports betting, internet gaming and video gaming terminals.
