I wouldn't want to hold any Internet-based stocks for "decades". I believe the life span of any public company to be 25 years or less, with Internet service companies being significantly less.
Certainly. There are also many that no longer exist.
From a summary I wrote of "Why Most Things Fail":
Of the 100 largest industrial companies in 1912, by 1995, 29 had gone bankrupt, 48 disappeared (mergers, acquisitions and so on), and 52 survived, but only 19 remained in the top 100. Once you discount the large number of small companies that fail in their first few years, the average lifespan for small companies is similar to that of large firms - and most of them eventually fail.
General Electric is actually over a century old. It was founded in 1892.[1] IBM is just over a century old, founded in 1911 (under a different name, as a merger of three existing companies).[2]
Boeing comes to mind. BMW as well. General Electric maybe. Actually plenty of things in the hardware space.
