Since it arrived on the scene in 2004 with a whopping 1GB of free storage space for users, Gmail has been funded by targeted advertising linked to the content of your emails, but that's going to change later this year.
"Gmail content will not be used or scanned for any ads personalization" at some unspecified point in the next few months, (opens in new tab), although you will still see adverts in your inbox - they'll just be generated using all the data the company has on you from other sources instead.
So why the change? Ostensibly it's to bring the consumer version of Gmail into line with of Gmail that Google offers to businesses: the paid-for option has never had inbox scanning and now the free option will follow suit.
It all ads up
In reality, Google probably now has enough data on its users from all that the contents of their inboxes just aren't that important or relevant any more. The move brings Gmail more into line with Google's other apps as far as advertising policy goes as well.
The makers of Gmail didn't miss an opportunity to tout the security protection and (opens in new tab) features that they offer to the 1.2 billion people on the planet with a registered address on the service. Meanwhile 3 million businesses have signed up to use G Suite, Google says.
