Stan is advertising that they have the whole of season 8 of Doctor Who available via their service. Strange but none of the images they are using to advertise this look like they came from season 8. Season 8 was the one with Jon Pertwee as the third Doctor, Katy Manning as his new assistant Jo Grant and Roger Delgado as the Master in every single story in the season. None of them appear in any of the advertising so either someone at Stan has made a mistake as to which season is which and used the wrong images or they have made a mistake and are identifying the wrong season.
The new season of Doctor Who that is currently being shown is season 35 and the images look like they came from season 34 instead of season 8.
