Kindle ebooks get easier

Finally, finally, Amazon is going to make it easier to load your own books onto your Kindle.

In short:

  • Amazon will start accepting EPUB files onto Kindles by “late 2022”.
  • It’s held out since 2007, as it tried to ensure the easiest way to read an e-book was just buying one through its own Kindle e-books store.

The details:

  • Owning a Kindle has been the default choice for millions: well-priced, capable, simple, and the standard for reading the latest thrillers to re-reading Lord Of The Rings or Twilight.
  • That said, as an e-reader, it was a bit of a walled garden: Amazon would happily let you upload files to a Kindle, but only if they were PDFs, or Word docs, or the old MOBI file type, which it has supported as a bit of relic since it bought Mobipocket in 2005.
  • Those restrictions meant if you wanted to buy some fun new or old sci-fi from some more ethical online store, you couldn’t use, quote “basically what everyone else in the world uses,” which is EPUB.
  • Amazon has been using a proprietary AZW3 file type (sometimes known as KF8) as its standard, but is now opening up to EPUB, a rare pro-consumer move.
  • Or is it just anti-antitrust? At best, it seems like more of a begrudging move that Amazon doesn’t really want to talk about. There’s no announcement or blog post. Instead, TechCrunch notes an update to a support page, here, Amazon’s Help & Customer Service page.
  • With this, we can all just email ourselves EPUB files, and Amazon will do the rest.
  • It’s not quite Apple allowing Android phones onto iMessage, but it is a big wall falling in the world of protected ecosystems.

How-to email yourself:

  • As an aside, for Kindle owners out there, you know you have a Kindle email address, right? And you can send stuff to it?
  • Here’s Amazon’s support page for all the details, but essentially, you can just send an email with an attachment and after a few confirmations, it’ll load up on the Kindle.
  • It works well! And it’ll work much more quickly and easily when it comes to support for EPUB.

Chart Tuesday

Here’s the state of Netflix mooching according to a survey of 2,209 US adults run by a firm called Morning Consult and turned into a chart by Statista:

  • In short, there’s a pretty healthy cohort who share passwords and/or use someone’s password.
  • As for 31% of people who don’t use Netflix, that base seems pretty rigid.
  • Hence, Netflix seems to eventually be targeting those who do use but without paying directly.
  • Some good news for Netflix not in this chart: Around one in three streaming subscribers would pay extra to legally share their password.
  • 10% of people in the survey said “Yes, definitely,” and 20% said “Yes, probably,” to paying more.
