Catalog log
Broadcast listing — not a TV Flash recap.
While the Doctor and Romana desperately rack their brains over how to escape E-Space, Time Winds strike the TARDIS, damaging it and K-9. Strangest of all, it allows Biroc, a hurt and hunted lion-man, to enter, phased in time, and set the control coordinates at zero-zero, sending the TARDIS into a milk-white void. Before running off, he warns of others who will be soon following.

Why this series still plays
A Time Lord, a police box bigger on the inside, and regeneration as infinite franchise life: Doctor Who launched from the BBC in 1963 and never really parked. Early black-and-white serials built the mythology; Hartnell-to-Troughton proved the lead could change without ending the show. The longest experiment in serialized reinvention — woolly, weird, endlessly renewable.
November 23, 1963, is a drop that never really parked. BBC's *Doctor Who* launched a Time Lord and a blue police box bigger on the inside, then treated the lead as renewable inventory. **Regeneration is the window.** Sydney Newman, C. E. Webber, and Donald Wilson were among the early architects. Early black-and-white serials built the mythology; companions, sonic screwdrivers, and cliffhangers became ritual. Rex wants woolly national inheritance. Fine. The business model is recasting without ending the show.
