Up until recently, being a fan of wrestling could be a very expensive and space-filling hobby. If you were interested in having copies of events to watch on-demand, then a home video library would be the order of the day, especially if you were a fan of multiple promotions. Whether they were obtained legally or otherwise, wrestling fans around the world would have had to keep piles of VHS tapes and later DVDs in order to keep up to speed on their favourite groups.
