The observable consequences of gauge-mediated supersymmetry breaking (
GMSB) are reviewed here. Implications of scenarios both with a neutral
ino and a slepton as the next lightest supersymmetric particle (NLSP)
are surveyed in relation to hadronic and e(+)e(-) colliders. We also d
iscuss the phenomenological consequences of the NLSP decaying slowly,
giving rise to delayed events in the detectors. The importance of dist
inguishing signals of GMSB models from those of the commonly discussed
supergravity-type theories is emphasized.
