The Silicon Valley rockstars you are talking about are usually customer facing, therefore media coverage is of interest for a broader mass. GlobalLogic provides services to companies, which makes them less commonly known. Meanwhile Hitachi is known in a certain niche at best...
The only reason I know that company name is because I think they sold hard drives in the past, and/or showed up on my BIOS screen. So maybe IT people know it too.
No - I'm afraid you are mistaken: what Hitachi sold was a "massager" - they were "distraught" to discover it's salacious "alternative" uses as it harmed their brand. Hitachi only agreed to continue selling the product as a joint venture (IIRC) if they removed the Hitachi name from it. So it's rebranded as just the "Original Magic Wand" now - no Hitachi :)
Quick tip: You can find a lot of places selling really solid new power tools at 50-75% off because of the name change. They will usually be sold now as "HPT", Hitachi Power Tools and they have to move the stock before they can sell the newly rebranded tools thus the discount.
Hitachi is well known because, like many Japanese and Korean companies, they make everything. In my neck of the woods they're a household name in machinery.
