See if you can you spot the subtle ways these tech companies changed their logos

Companies draw a lot of attention when they change their logo in drastic ways.

Logo updates don’t have to be a complete rebranding, though. Sometimes they are something as small as changing the spacing between letters or switching up some colours.

Can you spot how these tech companies changed their logos?

We'll start with something easy. Snapchat's original logo is named Ghostface Chillah. The name was inspired by Ghostface Killah of the Wu-Tang Clan.

In 2013, Snapchat gave Ghostface Chillah a makeover. Can you spot the difference?

Yep. Ghostface Chillah lost his face.

Google's logo tweak is one of the hardest to spot. Here's the before:

And here's the after...

If you didn't catch it, don't blame yourself. The company tweaked it by one pixel in May 2014. You can see the difference in this GIF from Gizmodo.

The main Google logo isn't the only one they have updated. This is an oldie, but goodie from 2010. Can you spot what they did to Gmail?

Here's the update in 2010:

Google shifted the alignment of the 'by Google' and changed the colours of Gmail's logo.

Facebook has messed around with its app icon before, but it's now updated its name as well. Here's the before:

Here's the after:

Did you catch that the 'a' changed? Facebook's June 2015 update made the a one-story, widened some letters, and swapped the F to match the favicon.

A month after joining Y Combinator in May 2015, popular question and answer site had an update: a new logo! Here's its original:

And here's the update. Can you spot the difference?

The logo is a little bit more spaced out, but it also had a typeface makeover. Its new look has a different Q and fixes the old problem between the R and the A.

MailChimp also has a super subtle one. It hired superstar typographer Jessica Hische to refresh its the type in its logo in 2013. Here's its original:

And here's Hische's updated MailChimp logo:

There's actually a lot of changes. Hische lightened the weight of the letters and thinned out the strokes at the meeting points. The type was also straightened a bit, but it still feels handwritten. At small sizes, the logo is much easier to read.

Pandora took the opposite approach of many of these updates. Here's its original:

Here's its 2013 update:

The type is bold now, and it switched to what looks like a sans serif font with some extra serifs tacked on to it.

While a lot of these companies had subtle tweaks, Mozilla tweaked its last logo in 8 different, but still subtle ways. Here's the original:

At this point, you should be a pro at this, so can you spot all eight changes?

The tinting on the globe is probably the most obvious, but here's the list from Mozilla of all eight:

These are just the subtle redesigns.
