Eye Gate Media educational cassette tape: Native American Studies. Cassette tapes, also known as audio cartridges or compact cassettes, were introduced by Philips in 1962. They revolutionized portable music and audio recording, becoming the dominant format for music consumption throughout the 1970s and 1980s. Their affordability and ease of use made them accessible to a wide audience, leading to the production of millions of albums and spoken-word recordings.

This particular cassette, "The Trail of Tears" by Native American Studies, produced by Eye Gate Media (a division of Herff Jones), likely represents an educational or documentary recording rather than a mainstream music release. Eye Gate Media was known for producing educational video and audio materials for schools. The copyright year of 1991 places it towards the end of the cassette tape's peak popularity, just as CDs were becoming the dominant format.
