Caesars Entertainment---the corporation that owns and operates casinos and hotels in 14 states and 5 countries -- is no stranger to the 500. But it’s been a few years since it’s found a home on the list. The gaming giant returns at number 365 this year having emerged from bankruptcy. In 20-18, Caesars revenues skyrocketed 73 percent. That jump was thanks in part to previous C-E-O Mark Frissora who helped dig the Nevada-based company out of bankruptcy.
