Just imagine how the world has changed in recent decades or centuries. The change is overwhelming. The high-tech innovations have surely created change, and many are now part of everyday life. Here is a list of 30 innovations that changed the world:
30. Solar Power
It’s becoming more and more possible to live green lives with solar power, and these once high-tech devices have become everyday tools in many places!
Global installed solar power capacity reached about 2.39 terawatts (TW) by the end of 2025, according to IRENA.
29. HIV and Cancer Treatments
Effective treatment helps people with HIV live long, healthy lives, and many cancers can be treated successfully, though outcomes depend on the type and stage. These diagnoses are not automatically death sentences.
28. Check Scanners
To piggyback off number 27, people can deposit checks through their phones! It’s a piece of cake, and many banks offer this feature through their mobile apps.
27. ATMs
ATMs let people withdraw cash and carry out basic banking tasks without visiting a bank branch. They’re well established in countries like India and Kenya too, though availability varies by location.
26. Credit Card Scanners
Small businesses can use card readers connected to phones or tablets to accept credit and debit card payments, including chip and contactless payments.
25. Uplighting
When people book a reception hall for an event, they are now able to give it a bit of extra special flair, something that party planners of yesteryear would die for!
24. Digital Photography
From professionals to those starting, everyone has the chance to share pictures with the world, and digital cameras don’t need film or a darkroom.
23. Fingerprint Clock-Ins
Employers can use these devices instead of paper time cards to record attendance and help confirm who is clocking in.
22. Auction Sites
The average person has the opportunity to become a prolific seller on auction sites such as eBay and marketplaces such as Amazon, and some earn enough to make online selling their full-time career.
21. “Live” Video Games
People from across the country and all over the world can communicate with each other as they play now, resulting in new means for friendships and even romance.
20. Online News
It’s no surprise that newspaper publishers have had to adapt to the popularity of online news, with many offering digital editions and subscriptions.
19. Online Shopping
With the world of online shopping growing at a huge rate, people wonder what will happen to traditional stores, and for good reason.
Online stores can avoid some physical storefront costs, but their overhead and profits vary by business.
18. Hair Removal Procedures
Whether it’s laser hair removal or electrolysis, there are options for reducing or removing unwanted hair, though costs and suitability vary.
17. Gamma Ray Surgery
Gamma Knife radiosurgery uses focused gamma rays to treat certain brain tumors and other conditions without an incision. It has been used for decades, and costs vary by location and coverage.
16. MRIs
With the presence of these tests, doctors can find medical problems in organs and soft tissues. Research into safety & accuracy continues.
15. E-mail
Here’s another one that has made the bridges between people much smaller, and email has become a routine part of e-commerce.
14. Pet GPS
Thought the last one was cool. Well, when a pet has a GPS collar, the owner can track where he or she is, though battery life and signal coverage can limit updates.
13. Pet Microchips
If a lost pet with a microchip implant is found, a vet or shelter can scan it for an identification number and use a registry to help contact the owner. The chip must be registered, and the owner’s contact details need to be kept up to date.
12. Vehicle Tracking Devices
With alerts that go off when individuals drive too fast or away from a particular zone (geofencing), parents can monitor teen drivers, and people can live their lives with less stress and more safety.
Not only are tracking devices used in cars, but also in vehicles such as trucks, airplanes, and submersibles.
11. GPS
GPS helps people find their way, and location-based apps use it for directions and delivery tracking. It’s already a routine part of everyday life.
10. WiFi
When you’re within range of a WiFi network with Internet access, you can connect wirelessly. But will we eventually get to a stage in history where the entire world is WiFi-ready?
9. Smartphones
From alerting you to your daily list of activities to playing games with friends, Smartphones are quite the little robots.
Smartphones can also connect to wearable devices such as Ray-Ban Meta smart glasses.
8. Tablet PCs
No matter how small your bag is or how far you have to go, it’s possible to bring your computer along with you and work on that blog every day and everywhere.
7. Online Schools
In addition to working online, people can also earn entire degrees online – even advanced ones! Remote internships are available too.
6. The Internet
The Internet has had a huge impact, and people use it for dating, banking, entire careers, and friendships, for example.
5. Home Security
Home security systems can send alerts to your phone and let you check cameras remotely, giving you more ways to monitor your home.
4. Facebook
People are already sharing information and pictures in ways they never have before, and Facebook shows no signs of stopping. Its parent company, Meta, also owns Instagram and has invested in virtual reality and the metaverse.
3. Keurigs/Tassimos
Will people stop frequenting their favorite coffee shops when they can make the brews at home? These devices make amazing Java, and they’re no longer a secret.
2. E-readers
Instead of picking a book off the shelf, people can download their favorite novels on Nooks and Kindles. Print and digital books continue to coexist.
1. Skype/Microsoft Teams
People no longer have to worry about not being able to communicate with those who are far away. They can chat with people across the world in real-time. Skype retired on May 5, 2025, and Microsoft directed users to Microsoft Teams Free.
