AltaVista was located below my company on a hill in Palo Alto. I used AV extensively and switched to Google not long after i learned about it.
Wow, DEC... gone nearly 30 years. They used to sponsor the Nightly Business Report during its golden age (Paul Kangas et al). Some years ago I saw a pile of tech arriving at the local electronics recycler, and there was a DEC workstation or two in the bin, looked to be in good shape. I passed.
