The most valuable companies over 100 years

Amazing. 100 years ago the largest, most valuable companies actually had products!. The only one I can see that made it through is Standard Oil/Exxon. By 2017 the top five are all tech--Alphabet is Google.

And Wal-Mart.  What change since 1950. When we were in Arkansas we visited the original Walton store, a 1950 Ben Franklin Five and Dime like the one in my home town of Mt. Morris many years ago, but Sam was ambitious and expanded. He didn't like the franchise's rules so started his own chain. It wasn't a Wal-Mart that killed my home town small businesses, it was a strike by a union at the printing plant, then changing technology, then moves to the south by the companies where everyone worked.
