  Since the launch of the Rossi X-ray Timing Explorer in 1995 our understanding
of jetted outflows has significantly improved. Indeed, relativistic jets are
now believed to be a fairly ubiquitous property of accreting compact objects,
that are intimately coupled with the accretion history. In this review, we
summarize the observational connections in X-ray binaries between accretion
flows and relativistic outflows (especially the relation with the X-ray
states). We emphasize those aspects that have significantly benefited from the
RXTE experiment, including the role that jets could play at high energies. We
also review recent observations of large scale relativistic jets that could
point to their long term effects on the interstellar medium.
