It was me that uploaded them and they have now all been removed by the BBC.
Although plenty of BBC dramas from that era have been released on VHS or DVD, ‘Shoulder to Shoulder’ has been omitted. Nor has the BBC made it available on iPlayer.
About ten years ago, in an effort to make the series available, I purchased a home-recorded VHS tape of the series, converted it to MP3 and uploaded it to Youtube. I did not monetarise it. The BBC removed all six episodes from my channel, claiming an infringement of their copyright.
But why does it care? As the BBC will not release it on DVD it is not losing out financially from it being available Youtube. What is more, many other programmes from that era have been uploaded by various individuals and have remained for years without the BBC removing them - even though the BBC sells them on DVD and therefore IS losing out financially - go figure!
The series was broadcast in 1974, then 1993 (at 11.30pm on Sundays!) and lastly on BBC4 in 2008, again very late at night (11.20pm). It's not been on for the past 15 years even though it's the ONLY TV series EVER made about the suffragettes.
Why is our public broadcaster, with its duty to educate, so determined to ensure that ‘Shoulder to Shoulder’ remains in obscurity and why does it thwart viewers' every possible means of watching it?
