The only problem is of course that Jacob Zuma appeared on ANN7, eNCA and SABC News as part of his PR press blitz.
"Exclusive" means to the exclusion of everything and everyone else - which means neither ANN7, eNCA or SABC News has a Jacob Zuma exclusive.
If a news channel claims a Jacob Zuma exclusive interview, it means Jacob Zuma is not appearing on TV news on any other channel in terms of giving an interview - and that you have an agreement or understanding that your interview subject is not sitting for multiple interviews on the same day, round robin style with different news outlets.
Jacob Zuma took turns to speak to and to give interviews to ANN7's Hajra Omarjee, to eNCA's Dan Moyane, and to SABC News' Vuyo Mvuko.
It means that ANN7, eNCA and SABC News as South African 24-hours TV news channels are all lying to their viewers, come across as opportunistic, and are getting shown up for making a false "exclusive" claim which is unintentionally hilarious.
