I own a few with dust on them, but the only boxed set I have purchased since the dawn of streaming has been the Horatio Hornblower series. It wasn’t on any service.
I also purchased Dogma, cause it’s awesome and it’s IP legal troubles mean you will never be able to stream this.
Quite a few, mostly at our cabin which doesn’t good enough internet to stream shows. Off the top of my head:
Venture Brothers,
Archer,
King of the Hill
Battlestar Galactica
The Americans,
The Mary Tyler Moore Show,
The Muppet Show and lots of others.
I have two: the (former) complete Beatles Anthology (which is just getting a reworked and expanded re-release), and a 7 DVD box called “The Blues” of documentaries about blues musicians/styles by renowned directors like Martin Scorcese (who also compiled the box), Clint Eastwood or Wim Wenders and others. I think it’s a bit of a rarity.
I have all three LOTR movies on DVD but they were purchased separately, not as a set.
I have a few partial TV series DVDs (5 seasons of LOST, 3 or 4 seasons of NewsRadio, a couple of seasons of Community) but no full sets.
I did have the complete Monty Python on VHS but not on DVD.
Oh! I forgot! We have that one, too; my wife bought it shortly after the series ran on cable.
All of my DVDs including box sets have been ripped to digital format. l still have the physical DVDs but they’re packed away somewhere (or in some cases are digital downloads). Going from memory, they include
… and probably many others that I’m forgetting. Also have many but not all Monty Python and Twilight Zone episodes, so not a box set as such.
I used to have a lot of physical media, mostly movies. Of the box sets that have since gone the way of Goodwill, I had:
Arrested Development
Battlestar Galactica (the new one)
Dollhouse
The Office
Dead Like Me
Wonderfalls
Band of Brothers (still own!)
Firefly
Veronica Mars
The West Wing
Felicity
Parenthood
Alias
Orphan Black
I’m sure there were more. I’ve transitioned to digital.
Bought almost no VHS or DVD’s over the years.
But we did buy the box set of Breaking Bad after the series had ended and we had seen none of it.
Super binge watching a show like that is the only way to fly!
The World at War
The Goodies
Red Dwarf (up to Series 8)
Several BBC Nature-David Attenborough series - The Blue Planet, Life in the Freezer etc
Classical Destinations
In my shelf of shit I’ll never play again because of streaming:
Babylon 5
Firefly
Aqua Teen Hunger Force
Mr. Bean
NewsRadio
The Venture Brothers
Lord of the Rings
Fawlty Towers
Red Dwarf
Battlestar Galactica season 1, still in its original packaging as I never got around to watching it.
Ahhh, gotcha. I know what torrenting is, I just misunderstood your timeline reference. My bad. 
I have a set of Beavis and Butt-head DVDs and a complete season of The Simpsons. The Simpsons one includes two of my favorite episodes, the one where Poochie is added to the Itchy and Scratchy Show and the one where Frank Grimes (Homer’s Enemy) tries to be a model employee but is driven mad by Homer’s incompetence and dies while trying to imitate him.
Yes, several, but I don’t know which ones are DVDs and which ones are video. They are on the top of a shelf in my bedroom, unwatched for years or decades, and I am not going to look now. I believe some season of Dr. House, the three LOTR, a five set of Louis Malle movies, something with dinosaurs/BBC are DVDs, Monthy Python almost sure are video, the rest I am not sure.
I have no video player anymore, haven’t had since the last time we moved house, and the only DVD reader I have is a tiny USB powered thing that goes into the laptop and I only keep in case I have to use a DVD for data. I hope it still works.
I have a various degree of DVD’s to Blu-Ray to 4K editions of box sets.
I suppose I’m old school cause I have 2 bookshelves sometimes 2-3 deep of media. I mostly collect them because they ban stuff and change stuff all the time. I also enjoy the extras and the commentaries.
To name a few I have; Dragon Ball/Z/Kai/GT, Supernatural, LotR in every media released (to my knowledge), Attack on Titan, Spongebob (I have mostly cause they banned episodes), My Name is Earl, Futurama, Mission Impossible, Planet of the Apes (both the older and newer ones), Batman motion pictures collection, Twin Peaks Complete, Whitest Kids You Know.
That’s what I could think of off the top of my head. Majority of my collection is physical video games.
Many. About 60-70% bought by me, and another 30-40% offloaded by friends who were moving and couldn’t be bothered. And it’s funny, because once I get them, I make a personal copy for my home NAS and then stream entirely from there.

Too many to list, but my X-files collection of every episode is probably the biggest.

SciFi TV from the early 1950s, some of which you’ve seen on MST3K
