Well in New Zealand we used to charge-per-byte but as things got cheaper this has largely gone away. Some of the cheaper how fibre accounts have something like a 100G/month limit but I guess it isn't worth the trouble to charge even here where bandwidth is much more expensive than the US.
Flashback: I was on Actrix which charged $5 per megabyte. Downloading Netscape Navigator 2 nearly bankrupted me.
I used to browse the internet with images disabled, which ironically gave me an appreciation for accessibility issues which served me well later in life.
When Xtra came out at $2.50 per hour, it was a complete game changer.
I remember when Xtra bought out their $27.95/month unlimited dialup plan.
It changed our internet browsing habits so much. With hourly charges, you would try to plan out what you would do before connecting and instead of reading webpages, you would save them to disk for reading later.
With unlimited, you could just sit there and browse. Or leave it on overnight to download files.
At some point we got a second phoneline and I was downloading torrents on dialup all day and night for years before we finally moved somewhere with ADSL in 2006.
