I kicked it off in 1994 with the first edition of Writing for the Media. And continued it with the second edition. But dropped it when I put together the third edition.
But today, after get yet another query about the history of the South African press, I've decided to (re)build the media milestones on Dipity. And to invite others to join the project.
So, if you'd like to contribute, just pop me a note.
