It is well known the pioneer for drifting is Mr. Tsuchiya from Japan. He may not have created it but he did make it known around Japan and in the world by using the technique while racing professionally.
After some digging we managed to come across a documentary of the man himself showing his skills to the public in the 90s. It looks to be a documentary made (independent) from the time on auto racing culture. It follows the Drift King on a day in a life type way. The quality is a little low is good for historical reference and just to se his skills around 30yrs ago.They Call Me King Of The Drift Shirt.
