It started before then. My school switched from a rather elegant 19th century (I think) design to something more streamlined that I never really liked around 2000. But I don't really disagree in general. I know when my company did a rebrand, one of the drivers was that the old logo had a lot of fine detail. (It also had some aspects that you couldn't unsee once someone mentioned them and it basically got the company's name wrong--which still gets people confused to this day.)
