Already, I'm going to break my own set of rules for this thread by posting the following video as it's not set in the North East. However, I could make a tenuous link to the North East as it involves Solent Blue Line, now BlueStar: a Go Ahead Group subsidiary whose offices are registered in Newcastle.

It's a video about the bus-wars which took place on the South Coast and the Isle of Wight after the industry was de-nationalised in October 1986 as part of the 1985 Transport Act. Originally, I was looking for a video documenting the Darlington Bus Wars but I couldn't find anything. If any such videos exist, then please post the links or let me know where I can find them
