The digital television transition has pretty much made the use of television antennas completely antiquated. There are still plenty of places using them, but it's only a matter of time before they're eliminated completely. The next generation will have no idea about how much of a delicate touch was often necessary to get a clear broadcast of your favorite show.
The phrase itself will probably last a long time, but checks themselves are rarely used today, except by large businesses. With the rise of online banking, customers have all the work done for them by their computer. Many people are completely unaware that the "balance" part of the phrase stems from the act of subtracting the cost of your purchases from your beginning account balance, and instead think it refers to simply keeping everything organized and stable.
Remember back in the old days, how you'd lift up the receiver and wait for the dial tone? Cell phones don't do that. This was a conscious effort on the part of those who brought cell phones to the masses, as they felt that no dial tone would keep people from feeling rushed to send their calls. This would mean less time was spent on the network, and thus kept it from getting strained. With land lines going the way of the dodo, future generations will not even know what a dial tone was, much less ever hear one.
"Ditto" is a simple word used by people when they agree with someone else's sentiment. It is already a pretty old-fashioned word, but its meaning goes all the way back to "ditto machines" which were a sort of hand-cranked copy machine invented in the early 1920s. Ditto machines were in widespread use all the way up to the 1980s but were eventually replaced by copy machines. To say "ditto" meant that your opinion was identical to your friend's, just like a copy made by the ditto machine.
Star Lord has done a lot of work to keep mixtapes alive, but tapes themselves are pretty much obsolete. Nowadays, the "tape" part of the word has been dropped, and people just make each other mixes or playlists. The sentiment is still there, but it's just not the same without going through the trouble of recording and transferring songs from actual sources. You actually took the time to make something with some physical effort for someone you cared about! Now, it's just a couple of clicks on Spotify and you're all set.
Chalkboards are definitely in wide use still and we love that, but they won't stay that way forever. Heck, even dry erase boards are starting to get replaced in places with "smart boards," which are basically giant tablets that a teacher can just draw on with their finger or a stylus. I don't think Quint would've been able to get everyone's attention in Jaws by running his nails down that.
We know that hipsters are actually doing a decent job at keeping vinyl alive (and that is probably the only commendable thing they've ever done,) but the nature of music releasing has pretty much eliminated the B-side. For those not in the know, a B-side was the flip side of a single. The A-side of the single was usually a song pushed by the record company with the hopes of it being a hit. The B-side was usually something a little less marketable, but still pretty great in itself.
Digital sales now just sell the single song by itself. If they do include something else, it's usually referred to as a "bonus track," and no longer as a B-side.
This one's almost entirely obsolete already. Calling 411 was what you did back in the day to get information about an area you were in and were unfamiliar with. You could get directions, restaurant recommendations, operating hours or pretty much anything. So to ask someone for the 411 meant to ask for information about something. Smart phones have removed this from the gene pool.
Carbon paper is still in use, especially if you've recently had anything done to your car or dealt with invoices. Still, most younger people don't know what it is and just know that they sign it and are allegedly supposed to keep it. Carbon copies were so ubiquitous at one point that even when computers became widely, used they were worked into computer systems. What do I mean? CC in your e-mail stands for carbon copy. I had no idea that this was true until I researched this article.
Tapes are no longer used by the average person, and thus they do not need to be rewound. There are very few instances in which you would tell a younger person to rewind something and not be referring to the concept of tape (maybe while using a rope or something, but even then you'd probably just tell them to wind it up, not rewind it). The word itself is on the brink of extinction.
The younger generation looks at this and calls it the hashtag. The older generation might call it the number sign or the pound sign. Hashtagging is integral to trending and metrics on social media, using the symbol as the number or pound sign is not. Those names for it are doomed.
Even if you have a cordless phone with a charging base, you don't have to really "hang it up" so much as put it back in place. The younger generation will never know the joy of being furious with someone and slamming down the receiver to hang up on them with gusto.
"Broken record" is kind of misleading; "scratched record" made more sense. When a record was scratched, the needle would get stuck in an infinite loop on the groove the scratch made, causing it to repeat itself over and over again.
...Maybe future generations will sound like a corrupted audio file?
You used to put money into a pay phone (yeah those were a thing) to make a phone call. Historically, the cost of a phone call was a dime. If you were calling the police to snitch on someone, you'd be then "dropping a dime" on them. This one was obsolete as soon as the price of a phone call was raised, but now it's even more so, since pay phones have been eradicated.
Even though Saturday was our day off, we kids used to get up early to watch cartoons. The practice of airing Saturday-morning cartoons began in the 1960s. In October of 2014, on the morning of October 4th, no Saturday morning cartoons were aired for the first time in over 50 years. Pardon me, I need a moment.
Smoking bans are rapidly spreading throughout the world and in many parts of the US it is virtually unheard of to allow smoking indoors anymore. We can't say that we will miss indoor smoking very much, but we do lament the fact that the amazing "smoking or non-smoking" joke from the movie Airplane won't make sense anymore.
Power windows have been the norm now for many years, though several manufacturers still make windows with manual cranks. My current car is 21 years old and it has power windows! So, we're rapidly reaching the point where younger kids won't ever know that you actually had to roll the window up yourself.
Tuners and Dials have not been present on televisions for decades. You could still recently tune your radio with a dial, but those have been pretty much phased out as well. "Don't touch that button" will have to suffice.
At one point, Kodak had a 90% market share of photographic film sales. The company was slow to transition to digital photography, and eventually had to file for bankruptcy and sell of many of its patents, despite having introduced the very first consumer camera. Their slogan, "Kodak Moment," referred to anything worthy of being captured on film. With the success of digital cameras and their lack of film, anything and everything is photographed... and let's be honest, no selfie is really worthy of being called a Kodak Moment.
