In what year did McDonald's launch its drive-thru service?

McDonald's launched its drive-thru service in 1975, which marked a significant innovation in the fast-food industry. The concept was introduced to cater to customers looking for convenience and efficiency, allowing them to place orders and receive their meals without leaving their vehicles. This service was particularly appealing in the context of increasing automobile usage and changing consumer behavior, making it easier for families and individuals on the go to enjoy McDonald's offerings. This move not only set a standard for other fast-food restaurants but also paved the way for the modern drive-thru experience we see today.
