Abstract: The new generation of optical and infrared interferometers have unprecedented angular resolution and sensitivity. I will review recent advances in studies of massive objects in the upper portion of the Hertzsprung-Russell diagram, including fundamental parameters of individual red and blue supergiants, first interferometric imaging of interacting binaries, and new views of dust and gas in strong stellar winds. We note that massive stellar evolution is still usually discussed in the context of single star evolution, despite mounting evidence that binarity is commonplace and likely lies at the root of many observed phenomena.
