What caused the trend of overdesigning in 00s?

I am not a designer, but I've noticed that over the last 5 or so years, minimalism has been king when it comes to design.
Before that I remember logos, posters, ads etc being very "cool" and stilized (as opposed to the quirky and fun look of the 90s). How did that become the standard and what caused people to realize that sleek and minimalistic is better?

Great design resource
