7-Eleven
In 1946, to help the company grow, the name of all the stores were changed to 7-Eleven to adjust to the stores' new hours of operation, 7 am to 11 pm. In 1969, 7-Eleven made a 24-hour store in Austin, Texas after an Austin store stayed open all night to serve customers. Later on, 24-hour stores were created in Fort Worth and Dallas, Texas, as well as Las Vegas, Nevada. In 1971, Southland bought convenience stores of the former Pak-A-Sak chain owned by Graham Allen Penniman, Sr. (1903–1985), of Shreveport, Louisiana.
