Hood River's economy has traditionally been based on three industries: agriculture, tourism, and sports recreation, but since the late 1990s, high-tech industries, such as aerospace engineering (e.g. Insitu and Hood Technologies), have become some of the largest employers. Long an agricultural center of the Pacific Northwest, Hood River historically was a hub of logging exports and fruit tree orchards. While lumber was the primary export for Hood River throughout most of its history, with the advent of forest protection measures such as the establishment of the Columbia River Gorge National Scenic Area, Hood River has exchanged most of its former tree cutting agricultural ways to focus more heavily on its apple and pear orchards as well as many wineries. Many of these local orchards and wineries, including Hood River-based The Fruit Company, are featured on Hood River's renowned "Fruit Loop".
