Betamax is a consumer-level analog-recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975. The first Betamax device introduced in the United States was the LV-1901 console, which included a 19-inch (48 cm) color monitor, and appeared in stores in early November 1975. The cassettes contain 0.50-inch-wide (12.7 mm) videotape in a design similar to that of the earlier, professional 0.75-inch-wide (19 mm), U-matic format. Betamax is obsolete, having lost the videotape format war to VHS. Despite this, Betamax recorders were not discontinued until August 2002. Betamax cassettes were available until March 2016, when Sony stopped making and selling them, alongside MicroMV.

P2 is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004, and especially tailored to electronic news-gathering (ENG) applications. It features tapeless (non-linear) recording of DV, DVCPRO, DVCPRO25, DVCPRO50, DVCPRO-HD, or AVC-Intra streams on a solid-state flash memory. The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card enclosure, so data transfer rate increases as memory capacity increases. The system includes cameras, decks as drop-in replacements for videocassette recorders (VCR), and a special 5.25-inch computer drive for random-access integration with non-linear editing systems (NLE). The cards can also be used directly where a PC card (PCMCIA) slot is available, as in most older notebook computers, as a normal hard disk drive, although a custom software driver must first be loaded.
Sony produces professional, consumer, and prosumer camcorders.
