The superluminal radio jets produced by GRO J1655–40 during a series of X-ray outbursts in 1994 were the first indications of a delayed form of relativistic outflows from black hole accretion disk environments. In this paper we review the relation between the radio jets and changes in the X-ray environment for the 1994 events in GRO J1655–40 and compare this behavior with similar X-ray-radio correlations that have since been found in GRS 1716–249, GRS 1739–278, and the 1996 recurrence of another correlated event in GRO 1655–40. We also discuss newly found radio-X-ray correlations in a galactic X-ray binary, Cyg X–3.
