Unison would be perfect if we found ourselves time traveling to the ’80s and needing to look up job listings, download software, or pose questions to an online community. That’s because Unison browses Usenet, the text-based precursor to the modern internet. Once the cutting edge of online interactivity, Usenet is now the domain of niche topics and downloads of varying degrees of legality. Unison makes it easy to grab video files, music, and other media, and its interface lets you smoothly navigate Usenet’s bulletin-board depths. Unfortunately, the web, the iTunes Store, streaming Netflix, email groups, and other, better services now limit Usenet’s appeal. Time travel remains elusive, so there’s little reason for others to get started on Usenet now, but Unison makes a great browser for Usenet regulars.
