Established in the late 1990s during the peak of the first dot-com boom, Bay Area Ghosts (BAG) initially emerged as a close-knit community of urban explorers and paranormal investigators. Operating from a modest warehouse in San Francisco’s South of Market district, the group garnered local recognition for documenting the “technological hauntings” of the Silicon Valley era—alleged spirits lingering in the decommissioned server rooms and Victorian-era estates of the Peninsula. Their early endeavors combined innovative signal processing technology with traditional spiritualism, establishing a unique position within Northern California’s distinctive cultural milieu.

By the mid-2010s, the organization underwent a substantial transformation, formalizing its status and expanding into immersive media and historical preservation. Their focus shifted toward the “Ghosts of Industry,” documenting the rapid transformation of the Bay Area and the remnants of its maritime and manufacturing past. Presently, Bay Area Ghosts, Inc. is celebrated for its interactive storytelling and digital archives, which serve as a connecting link between the region’s rugged 19th-century heritage and its high-tech future. While they continue to be a prominent player in the local “haunted” tourism circuit, their legacy is defined by a steadfast commitment to unraveling the concealed layers of San Francisco’s ever-evolving social fabric.
