 I'm Tom Merritt from Daily Tech News Show. Here are the top five greatest tech companies of all time. What's the greatest tech company of all time? Well, that's a matter of opinion, of course. And I can almost guarantee that your opinion is going to be different than mine. For my list, I weighed up things like longevity, innovation, impact. These are companies that fundamentally and sustained over a long time really fed the technology we have today. And I'm going to tell you right now, they are not the names you're expecting, folks. Here are the top five greatest tech companies of all time. At number five, Nokia. It has roots in the 1800s. It grew out of a company that made rubber boots and respirators. But the modern Nokia was founded in Finland in 1967 with four major businesses. Forestry, cable, rubber and electronics. Over the many years, it made many types of electronics, including TVs, computers, and of course, most famously, phones. Now, since the sale of its phone division to Microsoft in 2014, it has focused on network technology and health tech withings. Coming in at number four, IBM. From its roots is the Computing Tabulating Recording Company and Herman Holarith's Tabulating Machine Company. It is a lesson in how to pivot to stay true to your premise, not your product. They started making punch cards, and at various times the business was dominated by typewriters, calculators, mainframes, personal computers, managed infrastructure, and most recently, cloud computing, AI, data analytics and security. IBM has an impressive record of longevity. Up to number three, the Bell System, good old mob bell. It dominated U.S. telephony from 1877 until its antitrust breakup in 1983. It was once the biggest company in the world, was made up of AT&T and then the regional telephone companies in the U.S., but its tech prowess shown brightly in Bell Labs. Over its many decades, it developed things like photovoltaic cells, the calculator, the transistor, and even fundamental software theories and processes like binary code. I mean, we should probably do a top five or maybe a top 20 of the advancements made by Bell Labs. And it's not gone either. Remember Nokia? Nokia bought Bell Labs in 2007 and continues to operate. Sliding in at number two, General Electric. You can't leave out the company founded by Thomas Edison. Whatever you think of his actual inventiveness, GE brought the world light bulbs, record players, electric motors and expanded radio and television, as well as once dominating in home appliances. Its length and breadth of tech cannot be denied. And while it may be diminished from its height, it's still an operator in aviation, manufacturing and, of course, energy. At number one, Xerox. The 117 year old company has become a documents technology business, but at its height, it developed almost every technology you use today. The Palo Alto Research Center, or Xerox Park, developed the modern graphical user interface for desktops, the mouse, laser printing, ethernet and more. The Xerox Alto in 1973 was the first thing most of us would recognize as a modern personal computer. Now, Xerox's designs were better marketed by others like at Apple and Microsoft. But you have to acknowledge just how much came from these minds. You don't have Windows, the Mac, even the iPhone without what Xerox brought us. So you're saying, what about Intel? What about Microsoft? Apple? What about ARM? Nintendo? You can make great arguments for all of them. And if I did this list again, I might change my mind. But considering longevity, ability to continue to innovate or just a long term effect on the world of technology, I think these companies had the most impact.
