Discovery Health Network has purchased the cable rights to all 141 episodes of Chicago Hope, which ran on CBS from 1994-2000. Former cast member Hector Elizondo will kick off an eight-hour marathon of the soapy medical drama on Aug. 1. The series will then run on the channel three times a day — noon/ET, 7 pm/ET and 2 am/ET beginning Aug. 2. Hope previously ran in syndication on Lifetime.
