I want to know the answer to the following question:
Under what name was LaserDisc originally marketed?
All the background I'm provided with is that "Initially licensed, sold, and marketed as MCA DiscoVision (also known as simply "DiscoVision") in North America in 1978, the technology was previously referred to internally as Optical Videodisc System, Reflective Optical Videodisc, Laser Optical Videodisc, and Disco-Vision (with a dash), with the first players referring to the format as "Video Long Play".". Is that enough to answer the question?
Answer: yes
