A startup called Hovercast has helped political groups from Bernie Sanders’s campaign to the Wisconsin Democratic Party add interactivity to streamed events.
On Sunday, a coalition of progressive-leaning political groups hosted a fundraising event with performances by artists such as Patti LaBelle, Chaka Khan, Jason Mraz, and Herbie Hancock. In keeping with coronavirus precautions, the event—called Lift Every Voice—was online only, with performances prerecorded from artists’ homes or studios to maximize production quality.
