TEN’s Head of News and Current Affairs, Anthony Flannery, said: “The new TEN Eyewitness News app reflects the way viewers want to consume news, from wherever they are and at any time across the day.
“It also makes viewers part of our news. Being an eyewitness reporter via the TEN Eyewitness News app presents a unique opportunity and one which engages viewers with our news like never before,” he said.
