Dear Commons Community,
Over the decades, those of us who dabble in technology have seen a number of battles between company X and company Y compete for a market share by developing their own media formats. Among the more famous were the VHS/Betamax, CD/MP3, and HD DVD/Blue-ray. I stumbled upon this website which gives brief summaries of the ten more famous format battles. It is an interesting and quick read. See URL below.
