Complete Hill Street Blues Now Available on DVD
Shout! does really nice, fan-conscious packages. The show ran from 1981-1987, 144 episodes, contained here on 34 discs. There are extras, including a documentary and interviews and a handful of commentaries. The show was revolutionary, not just for bringing more realism to the cop show genre, but for its use of movie-style techniques, like overlapping scenes.
I wish Shout! Factory would do a complete WKRP in Cincinnati, because they’re the only company I know that would do it right. It would likely be pricey, with the music rights, but it would be worth it.
