This is The Overspill. I’m Charles Arthur, a freelance journalist, previously technology editor of The Guardian, but this is not a blog associated with The Guardian.

I’m available to write, speak, moderate events of all kinds, and do media training. (I’m not a charity, however, so unless your organisation is, please expect that I’ll ask to be paid to do any of those things.) You can find out more details on how to contact me through my personal website.

Want a sample of some of the things I’ve done?
• calculated how woeful sales of Amazon’s Fire Phone were (I reckoned 35,000 in a month based on publicly available data); within days it had cut the price by $200

• wrote about Huaqiangbei, the giant market in Shenzhen where you can get any electronics part you want (and the thriving market in not-quite-legit smartphones there)

• explained how “falling market share” can actually mean “growing number of users” in smartphones

• explained it again, with graphs

• explained how the smartphone patent wars work

• pointed out that BlackBerry’s Playbook tablet was a sales disaster, based on its accounts showing ballooning inventory: within days it was slashing the price.

You can find the full listing of thousands of stories I’ve written on Journalisted.

If you want references on speaking, moderating or media training, I’ll be happy to help.
