 Weekly current affairs program "Four Corners" began in 1961, followed in the same year by "Profiles of Power", a series of interviews with prominent Australians.Direct relays between Sydney and Melbourne, as well as Canberra, were also established in 1961, replacing temporary microwave relays as a means of simultaneously airing programs across multiple stations.Videotape equipment, allowing the sharing of footage with much greater ease and speed, was installed in each state capital by 1962.
