In the 1970s and 1980s, two video formats battled for dominance. VHS and Betamax offered similar functionality, but only one would survive.
The Contenders
Betamax (Sony, 1975)
Technical advantages: Better picture quality (250 vs 240 lines), better sound, more stable image, smaller cassette.
VHS (JVC, 1976)
Strategic advantages: Longer recording time (2 hours vs Beta's initial 1 hour), lower licensing fees, willing to share technology.
The Critical Difference: Recording Time
The most important factor was recording time. The primary use case wasn't watching movies—it was recording television.
NFL games and movies typically ran 2+ hours. Original Betamax recorded only 1 hour. By the time Sony extended to 2 hours (with quality reduction), VHS had established its advantage.
Licensing Strategy
Sony: Tight control, few manufacturers, higher prices, limited availability.
JVC: Actively sought partners, favorable licensing terms, multiple manufacturers, more competition, lower prices.
Network Effect
As VHS gained market share:
1. More VHS VCRs sold → More blank tapes sold
2. More VHS owners → Video stores stocked more VHS
3. More VHS rentals → More reason to buy VHS
4. Cycle reinforces itself
By the early 1980s, rental stores chose VHS decisively.
The Numbers
• 1980: VHS 60%, Betamax 40%
• 1986: VHS 90%
• 1988: Sony began making VHS VCRs
• 2002: Sony ceased Betamax production
Lessons
• First-mover advantage isn't everything
• Understand customer use cases
• "Good enough" at the right price often wins
• Network effects can be decisive
