Oh, 1999. Simpler times, those. IT departments were frantically prepping for Y2K, Jeff Bezos (or his head, at least) was named Time's "Person of the Year" and the tech bubble was getting ready to burst at the seams. That same year, the lights on Yahoo's "A nice place to stay on the internet" billboard turned on for the first time on the highway leading to the Bay Bridge. Those lights, which have seen their share of ups and downs for internet companies, will be turned off for the last time in the coming weeks. Clear Channel confirmed that there will, indeed, be vacancy in that space come next month.
