1. 1980s CD player
   1970s tape player
2. 1950s radio
   1920s video game

The first radios were just that ... radios. They didn't have CD player options, record players, or even 8-track players. They were simply conductors of radio waves, bringing your favorite radio programs to your living room every night.

1. Manual processor
   Word writer
2. Typewriter
   Typerloom

There were dozens of variations of the typewriter before the word processor was invented. Eventually, typewriters even allowed for an erase option that deleted mistakes. This was incredibly helpful to those who couldn't type with accuracy.

1. Wheelies
   Boardwheels
2. Shoewheels
   Roller skates

Way back when, roller skates were attachments for your shoes. However, safer versions were made that basically functioned as footwear. These days, rollerskates and rollerblades have been replaced with Wheelies and razor scooters.

1. 1920s radio
   1950s generator
2. 1970s vacuum cleaner
   1980s water receptical

Though not much has changed in the way of sound for vacuum cleaners, there are much sleeker designs. Some vacuum cleaners have even done away with expensive (and environmentally silly) bags.

1. The original CD player
   8-track player
2. Reel-to-reel tape recorder
   Record player

If you've ever seen a detective film that was shot in the '60s or '70s, you recognize these awesome tape recorders. While they were bulky, they were effective, and created a great sound recording.

1. Washboard
   Basin board
2. Tub board
   Rug beater

A washboard generally had a wood frame and a grooved metal surface. This made it easy to wash clothes. We use the term "easy" rather loosely here, as it would take most people an entire day to wash and dry a load of clothes with a washboard.

1. Electric brush
   Egg timer
2. Electric razor
   Moisturizer

The first electric shaver was patented in 1930 by Jacob Schick. This guy really loved a close shave, because he (and his company) created some innovative shaving products.

1. Stand mixer
   Sewing machine
2. Spatula
   Cookie Maker

While stand mixers haven't changed a whole lot in terms of what they do, their designs have changed quite a bit. These days, a stand mixer doesn't just mix. You can get attachments that allow you to roll pasta, grind meat, and shred cheese.

1. Grinding nuts
   Sifting flour
2. Separating eggs
   Boiling water

Nut grinders of the 1950s aren't much different than the nut grinders of today. However, the food processors of today can grind nuts better and faster (and with less physical energy) than actual nut grinders, so why bother?

1. Stapler
   Peppermill
2. Onion slicer
   Sewing machine

Over time, the design of the sewing machine hasn't changed very much. However, newer models of sewing machines offer many more stitch options​ and require less manual work to operate.

1. Can and bottle opener
   Tweezers
2. Thumb press
   Whipple

If you're old enough to remember your juice coming in a can, you know that you needed to put two holes in the top of that bad boy to get the good stuff. One hole was for pouring and the other hole to relieve air pressure.

1. Phonograph
   Calliope
2. Hearing aid
   Trumpet

In the late 19th Century, the phonograph or record player as it would become known, was a great way to listen to your favorite music or speeches. The phonograph was invented by Thomas Edison in 1877 as both a recording and listening device.

1. Letter opener
   Butter knife
2. Nail file
   Stick finder

On the second look, you may be telling yourself, "Oh, yeah, a nail file." While the design of the nail file hasn't changed much, the materials from which it is made have. These days, we get disposable nail files instead of the metal ones.

1. The Internet
   An old school alarm system
2. A rotary phone
   An alarm clock

While you may have seen the hilarious videos of young kids trying to figure out rotary phones, they were actually very advanced for their day. People no longer had to call the operator to connect with others.

1. Milk
   Soda
2. Water
   Vinegar

Back when it was delivered, milk needed more protection so it was put into thick, glass bottles to protect it from the elements. These bottles were returned (or picked up) whenever the next shipment of milk was delivered.

1. Blueberry Muffin
   Raspberry Rhonda
2. Strawberry Shortcake
   Cucumber Cathy

Strawberry Shortcake was sold with her other produce-inspired friends. The best part about these dolls was the fact that they actually smelled like the desserts and fruits after which they were named.

1. Global positioning swatch
   Pocket watch
2. Compass
   Rose

The compass was an amazing invention, but you had to know how to use it. A compass will only tell you which way​ is north. You have to figure out the rest.

1. Salt shaker
   Ice crusher
2. Bowl shaper
   Can opener

These days, we have the Margaritaville margarita machine to crush our ice for us. However, for those unfortunate souls of the past, an ice crusher was what was necessary to create the ultimate hosting experience.

1. Toboggan
   Sleeping mat
2. Sushi roller
   Snow stencil

You didn't need a license to go incredibly fast on your toboggan. These excellent little manual snowmobiles were great fun for kids of every class since the early 1900s. A toboggan is generally more narrow than a sled, and larger models can hold many children.

1. Bellows
   Icebox
2. Cold storage
   Freezer

You may have heard one of your elders refer to the refrigerator as the "icebox," and this is why. Of course, the older models of iceboxes were very fancy, and the refrigerators that replaced them were definitely not as cool (especially the green ones).

1. Pocket secretary
   Contact list
2. Card holder
   Rolodex

These days, you can scroll through your social media to contact those you know, or you can simply start typing their name (or nickname) into your phone and their contact info will pull up. Before cell phones, however, people had to alphabetize their contacts on their own in a Rolodex.

1. Pet rock
   Fobb
2. Gloomy Gus
   Han Solo

Pet Rocks were a huge fad in the 1970s. These inanimate joke objects were sold as live pets, and even came in a box with holes in it, so the little guys could breathe.

1. Monopoly
   Chance
2. Mousetrap
   Trouble

This game that basically shows the consequences of capitalism (money for one) was designed in 1933.

1. A floppy disk
   A hard drive
2. A carrying case
   A Mac Book

Once referred to as "old school memory cards," floppy disks didn't hold much, but with the programs of their day, they didn't need to hold very much at all.

1. Raggedy Ann
   Strawberry Shortcake
2. Weebles
   Little People

While this doll looks creepy, it was a great doll for little children. The doll was patented in 1915 but was so easy to make at home, there were plenty of knockoffs.

1. Mickey and Minnie
   Pee Wee and Chairy
2. Gumby and Pokey
   Bullwinkle and Rocky

Gumby and Pokey toys and products were all the rage from the 1950s through the 1990s. There was even a Gumby movie in the 1990s, and though it didn't do all that great, the toys always sold.

1. Discman
   Camcorder
2. Polaroid
   Walkman

The Sony Walkman allowed you to walk around with your music playing in your ears. It was compact (sort of), and it gave you the ability to ignore adults who were yelling at you. The iPod would later allow you to walk around without bringing your tape collection with you.

1. CD player
   VCR
2. DVD player
   Walkman

While certain vintage VCR tapes can be collectibles, VCRs are relatively worthless (unless you have the videotapes that go with them). VCRs were the original TiVos, which are already obsolete as well (thanks, Hulu).

1. Clown college kit
   Clown balloon
2. Bozo Bop Bag
   Punch-it

"Bozo the Clown" was a popular television show in the 1940s that featured, you guessed it, a clown named Bozo. His popularity spawned a line of products, including the Bozo Bop Bag, which would bounce back after you hit it.

1. Corn Popper
   Clean Maker
2. Go GaGa
   GearZooz

These playtime vacuum cleaners by Fisher-Price are still in production today. These beloved toys were great learning tools for toddlers. Children love mimicking adults ... until they get to their teens, that is.

1. Hobby Lobby
   Milly Mixin
2. Holly Hobbie
   Strawberry Shortcake

Originally a paper doll set with stick-on clothes, Holly Hobbie toys would later include Colorforms (shown here), dolls, porcelain figures, tea sets and more. Children loved her because she was full of promise and accessories (well ... hats). Fun fact: Holly Hobbie's creator was an artist and writer also named Holly Hobbie.

1. Nasty-Grams
   Cabbage Patch Kids
2. Garbage Pail Kids
   Billings Bodies

Garbage Pail Kids were the punk answer to Cabbage Patch kids. They gave children of the 1980s the ability to make fun of themselves while they collected cool cards and stickers.

1. Nintendo cartridges
   Joy sticks
2. Controllers
   Atari cartridges

One of the earliest home game consoles was the Atari 2600. It was sold with joysticks and cartridges. When we look at our iPads and Xboxes these days, we should be thankful for the crazy programming skills involved in creating the Atari consoles.

1. 1977 Citizen Quartz Touch Screen
   1985 Citizen Quartz Touch Screen
2. 1977 Casio Touch Screen V-80
   1983 Casio Touch Screen TC-500

Before the Apple Watch (long before, actually), there was the Casio Touch Screen TC-500. It had an alarm, displayed the time and featured a calculator all in one. While it didn't use WiFi, it was pretty ahead of its time.

1. Pulsar 14K
   Pulsar P1
2. iWatch
   Industrial Watch

This was the first digital watch on the market, and it boasted an 18-karat gold encasement. In 1972, it cost a whopping $2,100, which makes the Apple Watch look basically free these days.

1. Joanie
   Jamie
2. Stella
   Steffie

The Walk Lively Steffie doll is relatively unknown, but collectors seek it out. This 1970s doll with dark hair can be worth up to $800, in a mint-condition box. It really does pay to be Barbie's friend.

1. 1900s Basketball
   1910s Football
2. 1920s Rugby Ball
   1930s Waffleball

The original basketball was modeled after the soccer ball. The game was invented in the late 1800s in Massachusetts to help keep athletes in shape during the off-season.

1. Nerf gun
   Crossfire
2. Super Soaker
   Water balloon launcher

That's right, your super soaker from the 1990s could be worth up to $500. Who would have thought squirt guns are worth more than most Beanie Babies?

1. Apple I Series
   Apple II Series
2. Apple III Series
   Mac 128 K

This home computer was on the market for an astonishing 16 years. It was offered for personal use and public schools from 1977 to 1993. There were different models, but the Apple II Series sold 6 million units.
