Nintendo Wii: Sold like gangbusters.
64bit Processors: The computing standard.
Battlestar Galactica: Considered one of the greatest sci-fi series of all time.
Facebook: Continues to be the world’s leading social media platform by literally BILLIONS of users.
High Definition: HD only got even more HD.
iPhone: Set the standard for mobile smartphone form factor and function to this day 16 years later.
The point is you should read the article rather than going off of headlines. Each thing in the list states as much.
The HD paragraph literally states exactly what happened. As soon as HD had made it to mainstream (actual tvs, laptops, monitors) it was already outdated. They were saying to not overhype it because it will keep happening. And they were completely right.
64 bit they were complaining about being overhyped because it was. Until you were able to get almost any app in 64 bit it was useless for all but the most tech savvy.
No one is ignoring the success of facebook. they're saying that facebook as a social network was overhyped. It wasn't the first, there was nothing remarkable about it. Just because Cavendish bananas are the most popular and most successful bananas of all time doesn't mean other, very good, very tasty bananas didn't exist before them. Cavendish bananas are just successful.
