Second Doctor comic stories
When the first doctor regenerated into the second in 1966, TV Comic changed the face of the doctor in the comics to suite the change in the show's history, although kept the same companions, the doctor's grandchildren like in the TV series, John and Gillian. They were soon replaced with Jamie McCrimmon, to better match with the TV series of Doctor Who.
