1978: The 15th Anniversary
The 15th anniversary celebration was not quite as splashy, but it was celebrated nonetheless—or it was at least planned to. Coinciding with the broadcast of the 100th Doctor Who story, “The Stones of Blood,” to mark the occasion, a scene was pitched to be added into the story where Romana conjures up a birthday cake for the Fourth Doctor in the TARDIS, to mark his 151st birthday. However, Doctor Who’s producer at the time, Graham Williams, nixed the idea.
