betamax vs vhs

Perhaps the biggest product war on the modern consumer's mind is the ongoing battle between Mac and PC. From developers' conferences to television commercials, Microsoft and Apple are actively engaged in a constant tug of war for customer loyalty. Though most of us are familiar with this heavily popularized competition (the more silly aspects of which are making their way to YouTube memes), substantially fewer of us are likely to remember a time when a very different sort of format war was being waged: The war between VHS and Betamax. The period of time between the late 1970s and early 1980s saw intense competition between these two home video formats, with VHS eventually emerging as the winner.

The Competitors

In 1975, Sony released the first ever successful home VCR. Known as the Betamax, these video cassettes contained 1/2 inch video tape inside their hard case, and had a standard length of 60 minutes. With the early popularity of the Betamax among TV enthusiasts, Sony seemed to have found a sweet spot in the home video market. It wouldn't be long however before the technology's soon-to-be arch rival appeared on the scene to challenge Sony's place in the living rooms of home theater consumers.

Enter the VHS (Video Home System) a new VCR format from JVC released later that year. The VHS featured several superior features over Betamax, including a longer playing time and faster rewinding/fast-forwarding. Despite Sony's attempt to standardize the Betamax format, including an appeal to the Japanese Ministry of Trade and Industry, JVC refused to conform and went ahead with its VHS format. The decision to go it on their own and reject Sony's standard format was the shot that started the long and intense war between the two companies.

The Battle For Length

The battle for superior format was not fought on marketing slogans and clever advertisements alone. The bulk of the competition stemmed from recording length, for which VHS has the upper hand. A standard VHS cassette could hold up to 120 minutes of video while Betamax filled up at around 60.

RCA entered the market looking to create a cassette that could hold 240 minutes of video. Having heard of the Betamax format, RCA executives spoke to Sony about the possibility of a 4 hour recorder. Having limited technology to work with at the time, Sony told RCA that the only way it would be possible would be to cut the tape speed and track width in half. The only issue with doing so is that picture quality would be significantly diminished, a compromise that RCA found unacceptable.

Having ruled out Betamax, RCA turned their attention to JVC, hoping that their new VHS format would be up to the four hour recording task, but to no avail. JVC also decided against the lower picture quality that would be required for such a long recording time. RCA eventually went on to develop the technology themselves and market it for $999.00.

The new four hour RCA recorder sparked a war over length, forcing Sony and JVC to ramp up their efforts to create longer recorders just to keep up with RCA. It took some time, but eventually Sony's was able to offer 5 hour recording. This was a good effort, but JVC's VHS went on to take the top slot at 10 hours. Ultimately, this allowed the consumer to save money by switching to VHS, as one 10 hour VHS tape cost less than two 5 hour Betamax cassettes.

Picture Quality

Recording length was only one of the major considerations consumers had to make when selecting a video cassette format. Picture quality was the second biggest factor, and it was here that Betamax began to see its demise. Having already lost to VHS in the realm of recording length, Sony would have had to crush VHS in picture quality to make their system worthwhile. Unfortunately for Betamax, this was not the case.

Betamax featured 240 lines of horizontal resolution while VHS featured 250 lines. This minuscule difference made the formats almost indistinguishable from one another in picture quality. VHS, having achieved longer recording time and identical picture quality, was beginning to emerge as the winner.

Rental Availability

The final nail in the coffin for Betamax came with the availability of rental machines. At the time, it was estimated that 70% of the VHS systems in homes were rented. Because the systems were so expensive to purchase (around $3,900 in today's dollar) it simply made more sense to rent the ever-evolving technology and guard against obsolescence.

JVC made their recorders widely available through the high street rental shops of the UK.  At the same time, the stores found it considerably more difficult to get hands on Betamax machines. Betamax also came with contingencies, such the the need to buy a TV with the machine, an expense the rental shops did not want to incur. The sheer availability and superior recording time of VHS resulted in the format taking 70% of the market long before Betamax began to appear in the rental shops.

By 1981, Betamax began to sink into obscurity. VHS, boasting twice the recording length, identical picture quality and far greater rental availability was the clear choice for most consumers. Over the next several years, Sony's sales of Betamax fell further and further until it was clear that the technology was no longer profitable to produce. By 1988, Sony was forced to abandon its creation and conform to the market, creating its own VHS recorders to compete with JVC.

In some smaller markets, such as South America and Japan, the Betamax format was still in production until 2002. The only remaining product to use this format today is the Betacam tape, a widely standardized cassette tape used for video recording. Recently however, even this format has begun to be phased out in favor of digital recording technology.
