With foresight, Sears would have evolved their mail-order catalogue business into an Amazon-like online biz.
Sears Roebuck (I worked for them 1982 - 1986) was the #1 catalog and they were called "the Amazon of their day". They did indeed miss a HUGE opportunity with the advent of the Internet. A smart marketing executive would've seen Amazon's start where they sold books online as an opportunity to put their entire catalog online, but nope. They missed it.
And where's Sears today? Every single one of 'em within 20-25 miles of me closed and is gone.
