Peak of hype/excitement - many things have their technical peak (most units sold/most units in the field) after the real "popularity peak".
CD-ROM drives first started not being put in Mac laptops in 2008, so the peak "units sold" would have been somewhere in the early 2000s. But by then Internet speeds were fast enough and other methods existed, so they were waning in popularity/excitement.
I remember upgrading from a 4x to 24x, and being excited for the much faster data transfer rate. What I didn't anticipate was the fact that it sounded like a jet taking off when it spun that fast! I figured out how to ratchet it down to 4x and kept it there unless I knew I'd need a fast sustained rate for something like copying hundreds of megs. It wasn't worth the noise for smaller transfers.
1994 was still solidly in the floppy era, and getting a CD-ROM was huge, even larger than some hard drives at the time.
If you had a CD-ROM drive in 1994, you were king.
