ITC obviously weren't keen to promote the series since it had been cancelled. Even if the show did run for 26 episodes it wouldn't have made that much difference if so many networks declined Joe 90. ATV Midlands first showed the series on 21st September 1969 at 5:30 PM, who was served the best of the Anderson repeats.

Granada and Southern Television were the only other networks to have shown the series, again around 5:30 PM.
Repeats ended in ATV and Southern in 1972, with Granada in 1975. In fact, most of the transmission orders were made on the ITC Recommended broadcast order as the series has little continuity between itself to set an order for the episodes. There were also repeats in Australia on ATN Channel 7 on Saturday mornings in 1972 - however, these were the only broadcasts outside the UK for the show.
