8 track cartridges were a very popular domestic audio format in the United States, although there were also sold in the UK and Europe. The growth of the 8 track was synonymous with its use in car industry, as it allowed people to listen to music on the move.
Although phased out in the early 1980s as CDs became increasingly popular, the 8 track retains a cult following, as demonstrated by this video which takes a virtual tour around the 8 track museum in Dallas, Texas, USA.
At Great Bear we are equipped to transfer 8 track cartridges and NAB cartridges which were used primarily in professional contexts, such as to play jingles at radio stations.
