I should have added this was back in 2010 or so, I don’t think it was as common to be able to open PDFs in browsers without an addon.

I remember sometime after 2014 I was just able to open PDFs without any additional software.

I used to work IT at a school and reports were emailed to parents as PDFs.

We got a complaint from a few parents saying things like, why are the reports PDF? Not everyone has Acrobat Reader, you should be sending these out as Microsoft Word files.

I then had to tell them that unlike Microsoft Word, Acrobat Reader is free to download and install. Anyone can get Acrobat reader or another PDF viewer, but not everyone just has Word on their device nor are they willing to buy it.

I didn’t mention the part about a Word file is easy to just edit.

I’m also going to assume that some of them are using a work laptop where they have Word installed and no admin rights to install a PDF viewer and too lazy to ask IT.

I’m not entering, just seeing what’s going on.

That’s just the back of one of the newer (2011) bus designs in London.

I say newer but I’ve been here since 2014 and I don’t remember seeing these until a few years later.
