Is it live or is it memorex?

The phrase "Is it live or is it Memorex?" originates from a 1980s advertising campaign for Memorex, a brand of audio tapes. It poses the question of whether a sound is being experienced in real time or is a high-quality recording. The slogan emphasizes the fidelity of the product, suggesting that the recorded sound can be indistinguishable from a live performance. Ultimately, it highlights the advancements in audio technology and the debate between authenticity and reproduction.
