Every time a new format competition breaks out (HD DVD vs. Blu-ray, etc.), it gets compared to the VHS vs. Betamax war from the ’70s and ’80s. Betamax was a format developed by Sony (SNE), and enjoyed a lack of competition until JVC came out with VHS in 1976 and started the format war.
Of course, that all became irrelevant when DVDs rolled around by the new millennium.
And heck … those barely lasted a decade before Blu-ray came in and threatened to change everything again.
