Back in 1993, there was no YouTube, Facebook, or Twitch, so companies like Microsoft would have to get creative if they wanted to do a live video broadcast.
That's why Microsoft held the DevCast, a satellite-broadcast telethon event.
The company's employees would demonstrate the latest and greatest advancements to Windows and the Office suite, and developers could call in live and ask questions.
The DevCast of 1993 had a very, very special guest even if they didn't know it at the time — Satya Nadella, who would go on to become Microsoft's CEO just over two decades later in 2014.
In his segment, Nadella pitches developers on using Excel with Microsoft Visual Basic to make new work apps for the Windows NT operating system.
This video was resurfaced earlier today by Fast Company, as part of the magazine's extensive new profile of Nadella.
