Four trends are accelerating change in U.S. museums: 1) indoor navigation and location-based services, 2) new ways of seeing like 360 video, 3D, AR, VR, 3) external pressure from grassroots initiatives and network effects on social media, 4) internal pressure to undergo a digital transformation and develop a digital culture. Museums are experimenting with technologies like indoor maps, augmented and virtual reality to improve the visitor experience, while social media activism and informal networks also influence museums to change and adopt digital strategies.
