Remember when crypto was hot and everything had crypto.

Remember the Internet was first hot and everything was iThis or Active That. iPhone still has i.

Remember… well not, me, I wasn’t alive… when radiation was cool and Radioactive was in.

Everyone always wants to be cool.

My favorite was block chain. A company I used to work for that was not a tech company, suddenly going on about the block chain. I saw former, non technical colleagues that were still there write long authoritative LinkedIn posts about the advantages of the block chain and it was incredibly cringey because I am not sure what they thought the block chain was, but I am confident they didn’t understand it at all.

E-something was the big trend before i-something and we still have ebay and email (although only the former is a brand name).

Before the iPhone was the iPod, and before the iPod I had an iRiver mp3 player. There was certainly a trend and only Apple's product survived that one.

Because the trend started with the iMac.

i<Something>.com was very common during the first dot-com boom. "e" prefixes were also common but I think "i" was more prevalent.
