When the establishments closed down in the hot summer months, the three men turned their attention to ballparks, the first being Offermann Stadium, and the creation of the sports concession industry.

In 1930, the company entered into its first major-league deal by signing an agreement with the Detroit Tigers to handle food service at Navin Field.

The Jacobs brothers expanded their business in 1939 by acquiring a racetrack, marking the beginning of Delaware North Companies Gaming & Entertainment.

In 1972, after negative press over alleged connections to organized crime in Sports Illustrated and the Arizona Republic, the Emprise company was convicted of federal racketeering charges over the purchase of the Frontier Hotel in Las Vegas with members of the Mob.

In the late 1990s, the company worked toward becoming the largest racino operator in North America by adding gambling to some of its racetrack properties.

Thereafter, the company entered the European travel hospitality market opening outlets at Gatwick, Heathrow, and Edinburgh Airports, and the Euston Railway Station.

Two Top, Buffalo Bus, Rendezvous, The Best Western, and the original Holiday Inn were family run businesses with winter access contracts to operate in Yellowstone National Park prior to their acquisition.
