As I read this article in TechCrunch about Snapchat, I wondered how interesting it'd be to see the amount of money a service has made selling your attention on a monthly basis in a similar way that we can see how many megabytes of data we've used on our mobile phones monthly (per application and really easily on Android especially).

So, with 150M active monthly users and a target of $300M in revenue for 2016, Snapchat is aiming to sell each user account ad placements of an average of 17 cents a month. That seems really reasonable. I'd pay 17 cents to use it monthly. It's like $2 a year. Sure. But, how much higher can it go? Link
