Lois Hart and David Walker: The married team of Hart and Walker co-anchored CNN’s first newscast on June 1, 1980. Hart nervously stumbled through the sign-off from that first show, apparently unsure how to do so on a 24-hour news network. Hart and Walker left CNN in 1989 to join CNBC, where they then anchored that network’s first newscast. The couple retired in 2008.
