The cartoons and TV shows of the old days are always subject to the Nostalgia Filter, so they may or may not be as good as modern works. But the changes in technology and computing are undeniable, and not just in the Internet / connectivity, either. I was born in '81, so I remember playing around on an Apple II greenscreen and 5 1/4" floppy disks. Now I'm (making attempts at) watching HD anime stored on terabytes'* worth of hard drive space. And that's after going through a primitive DOS GUI on a 286PC, Windows 95 on a couple of machines in the mid-90s, and Windows 98 on my previous PC (2000-2005, R.I.P.). Still haven't moved beyond XP.
Console and PC gaming have undergone similar shifts as well. Music-wise, I still have cassette tapes recorded off vinyl records from my parents' collection or the library in the mid-90s, as well as commercial cassettes, CDs, and .mp3s.
CARTRIDGES! (blow that shit before putting it in to make it work better) - Remember reloading your NES game like 10 times and celebrating once it worked?
I still do that, although mainly with my SNES. Although mine's a 2nd-model SNES I bought in 1999, not the original one my brother and I got way back in '91. I don't keep up with the times in gaming though -- I don't have any consoles newer than PS1/N64, and I don't play PC games more advanced than Starcraft and various visual novels.
Oh, and the movie you're looking for is
The Wizard. "I love the Power Glove, it's so bad."
*I don't think we even knew what a terabyte was back then. I'd heard of terawatts from Star Trek:TNG, but terabytes may as well have been ridiculous imaginary numbers like "gazillions."
