In the 1980's and 1990's, I collected VHS tapes. Below is a photo of what I had at the peak - just before I threw them away. By 2015, their time had long passed.
I bought movies, but mostly music video content. I used to visit a music store in Tel Aviv which sold "bootleg VHS tapes" - a rarity for this music collector. The quality was ok at best, but they were cool. Eventually, massively improved dvd versions came out and VHS tapes became obsolete.
By 2016, I was done buying physical media.
In the era of streaming, what is worth collecting as far as movies and music video content?
You don't need to keep copies of every "good" movie you see. Yes, Netflix and other services are constantly shifting movies in and out of circulation. The question to ask is:
Will I want to watch this video/music/concert at least once every year or two? By the time I hit 40, that list actually shrunk - in a good way. I won't be watching The Goonies or ET as often as I did in my teens. For me, it is the big series that I like - Marvel, Star Wars - and the classics that I grew up on - Willy Wonka & The Chocolate Factory, the Fletch movies. While I love Animal House, I've seen it too many times to count.
Pink Floyd's The Wall didn't age well. The internet kinda ruined the 1984 scenario. :)
James Bond? Yes, especially the 60's to 90's.
In an era of streaming, my "desert island movies" are more than 10 but less than 100.
Next tip - try to get the highest quality versions of the movie - up to a limit. A 35 GB version of The Wizard of Oz won't be much better than a 4 GB version - unless it has cut scenes and a documentary. 4 GB (dvd) is enough for everything until this past decade - as a rule of thumb.
Collecting movies in the era of streaming is a balancing act - what do you need? For the rest, find it on your streaming service or just watch random clips on YouTube to get the nostalgia out of your system.
One thing that is definitely over - burning movies and concerts onto physical media. While I miss those days, I was so happy to delete my last cd/dvd burning software!
Enjoy your movie collection!
