CED (Capacitance Electronic Disc) SelectaVision Videodiscs were a type of home video format that was popular in the 1980s. They were similar in appearance to vinyl records and used analog technology to store video and audio. CEDs were a precursor to modern DVD and Blu-ray discs and were eventually phased out due to the rise of VHS tapes and later, DVDs. However, CEDs remain a collector's item for some film enthusiasts and are known for their unique retro aesthetic.
