In April of 2011, SETI announced that due to budgetary constraints their radio telescope array would be set into hibernation mode.
SETI has traditionally cost about the equivalent of one attack helicopter per year. SETI@Home has used a distributed computing model and the public's computers to analyze the signals.
SETI has looked at only a fragment of the sky.
