Towards the end of 2017, the world was taken back by the fact that Apple released the new iPhone under the name iPhone X and not the expected iPhone 9. The latter should have been the successor to the iPhone 8 in their sequential naming system.
However, Apple is notorious for their unlogical naming strategies for its products. The iPhone X was a revolutionary product in the sense that it featured a drastic new design change. This included no home button, a new shape, its size and, of course, new features as well.
Apple wanted to take full advantage of convincing its customers that the iPhone X was something revolutionary and not just an updated iPhone. Naming it the iPhone 9 would have not had the same marketing impact, according to Apple. Furthermore, 2017 marked the 10 year anniversary of the iPhone, which played a major factor in its naming. Also, they used a roman numeral in the iPhone's name, another first for Apple.
Furthermore, this is not the first time Apple has done this with the iPhone range either. Do you ever remember there being an iPhone 2? Probably not, because it didn't exist. The first iPhone, launched in 2007, was simply called the iPhone, the next model was called the iPhone 3G, which had nothing to do with the familiar sequential naming system we use today, it was called the iPhone 3G because it featured 3G network connectivity. Thereafter, Apple released the 3Gs which featured a few extra features. Then, Apple released the iPhone 4, which would go on to carry the sequential naming sequence right up to the iPhone 8, where it would break away to the iPhone X.
And now, in 2021, with the release of the iPhone 12, it seems as we are back on a sequential naming system. But don't be surprised when Apple decides to throw a spanner into the naming works yet again...
