From the Graveyard
You just read about T-Mobile US. One of the companies whose work it now carries:
Sprint Corporation built National wireless, long-distance and enterprise carrier. What became of it?
Sprint Corporation brought National wireless, long-distance and enterprise carrier to Telecom. That work was distinctive enough to lead to its merger with T-Mobile US for US$26B. The standalone name now passes into the archive — but the team and technology continue inside T-Mobile US today. One of 430 names here whose work outlived the company.
From the Technology Graveyard
You just read about All. A technology from the archive that helped get us here:
Google/Alphabet Project Loon served 2011–2021. What ultimately replaced it?
Google/Alphabet Project Loon solar-powered balloons drifting in the stratosphere (~20 km), steering by rising and falling into different wind layers, relaying LTE from ground stations to phones far below. Its job passed to Unit economics — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
