Four years ago, taking pictures of brunch was weird. But on Oct. 6, 2010, everything changed.
Monday marks Instagram's 4th birthday, and to celebrate, it's time to take a trip down memory lane. Instagram gave TIME a time capsule that goes back to the early days of the photo-sharing app. The 13 most popular hashtags of 2010 show that while some things change (um, #iphone4?), some never will (#cat forever):
The Internet loves felines, now and forever
Now we have polar vortexes to worry about
A Silicon Valley favorite
About that time again
It will never end
We're now kind of more into #TBT
Remember a time before Candy Crush?
This one provided a lot of Halloween costume inspiration
The show will soon enter its final season
People love capturing natural occurrences
People continue to up their Thanksgiving Instagram game
With all of Instagram's filter offerings, it's now kind of hard to resist
