In this blog post I write about a key mistake I think Yahoo made during my time there in the late 90s to mid 00s, because I think there are lessons there which are still very much relevant for today's modern web.
I worked at Yahoo between 1999 and 2006. I'd say for the first two years we had a pretty much unparalleled opportunity. For the next two years it was probably on the verge of still being able to deliver on that, despite some existential challenges, and then for my last three years there I would say that it started down the long road of utterly losing its way. (Read about Brad Garlinghouse’s Peanut Butter Manifesto for a great commentary on that from 2006)
