LED Lightbulbs
LED lightbulbs hit the consumer market in the early 2010s. They were pitched as eco-friendly and energy saving, but a lot of people didn't like the blueish glow. So, color-changing Smart Bulbs were also introduced in this decade that totally changed the lightbulb game.
Ring Doorbell Camera
It's uncommon to see a block without at least a few Ring Doorbells. These are recording your front step 24/7 and help deter package thieves and break-ins! When they do happen, the police will usually have the footage of the crime to help the case. Fun fact: founder Jamie Siminoff was rejected on Shark Tank for this product. Five years later, Amazon bought it for $1 billion.
