The Origin of Video CD (VCD)

Posted on by hddvdsupport

The Video CD (VCD) was introduced in 1993 through a collaboration between tech giants Philips, Sony, Matsushita (Panasonic), and JVC. This format was among the first to distribute movies and video content on compact discs, offering an affordable and durable alternative to VHS tapes.

While VCDs gained moderate traction globally, they became particularly popular in regions like Asia, South America, and parts of Africa, where they served as a primary medium for home entertainment before the widespread adoption of DVDs.

Continued Production of VCDs

At HD DVD Revived, we continue to press new VCDs, preserving this format for enthusiasts and specific markets. However, the production of new VCDs has significantly declined worldwide. Most major manufacturers have ceased production in favor of more advanced formats like DVDs and Blu-rays. As of now, there is limited information about other companies actively producing new VCDs.
