Well, body text in browsers now tends to be set in larger than the long-held default of 16px mostly because so many people have not only larger screens but denser screens than we did twenty years ago. I tend to land around 18 or 19px for body type, although that depends on the typeface and use case. (A lot of what I'm "typesetting" for the web is long-form fiction and it turns out that going a little bit bigger than "standard" often increases readability, although just a little.) But I don't know that this is really a "trend"; Apple.com's body font size, for instance, appears to be 17px. If you actually look around the Goldman Sachs Design web site, they're actually using a surprising amount of 14px text as body text -- if anything, I think their design standards are for text that's too small, not too large. (And, no, I really don't think Hacker News's default 12px body font is reasonable; I view this site zoomed to 115% or 125% normally.)
