Doctor Who (season 22)

The twenty-second season of British science fiction television series "Doctor Who" began on 5 January 1985 and ended on 30 March 1985. It opened with the serial "Attack of the Cybermen" and ended with the serial "Revelation of the Daleks". The season returned to the traditional Saturday transmission for the first time since Season 18, but for the first and only time in the series' first run it featured 45-minute episodes in its entirety. During transmission, BBC One controller Michael Grade announced an 18-month hiatus for the series, partly citing the violence depicted in the stories of the season.

Synopsis.
The season mostly focused on Peri trying to adjust to the Sixth Doctor, who is still having trouble "getting his head on straight" while they're on adventures.
Serials.
The series moved back to once-weekly Saturday broadcasts. All episodes were 45 minutes long, though they also exist in 25-minute versions. Although there were now only 13 episodes in the season, the total running time remained approximately the same as in previous seasons since the episodes were almost twice as long.

Supplemental episodes.
A specially written segment produced for the BBC children's programme "Jim'll Fix It" featuring Colin Baker in character as the Sixth Doctor. It was broadcast on 23 February 1985. It is not generally considered to be canonical by "Doctor Who" fans (although a book in the "Big Finish Short Trips" series nevertheless features a sequel to it).
