Every year at Web 2.0, Morgan Stanley analyst Mary Meeker unveils her Internet Trends. I will not rattle down the entire list (the briefest of brief summaries over here at TechCrunch) but one thing that is really noteworthy as compared to last year’s edition (which I briefly covered here) is that mobile takes centre stage: in 2009, she started covering mobile in earnest on pages 28 et seq. This year, it is topic # 2 (but even topic #1 [Globality] has more than 50% mobile in it).

Now, the learned readers of this blog have (I suspect) known this all along but it is good to see that one of the more influential analysts of the web at large “decrees” this on the Web 2.0 (sic!) stage, too.

And it is of course blindingly obvious: large parts of the world leapfrog the desktop Internet simply because they do not have access to desktops. The access instrument of choice is mobile. And these parts of the world just happen to be the ones where most of the growth occurs.

Incidentally, Meeker’s third point was social ecosystems. And there as well, we are seeing the huge impact of mobile. If you take Tencent, China’s IM/Social Networking solution of choice with a whopping 637m active IM users, and compare that with the Chinese Internet users (384m), we have a delta of 250m people who are accessing this via mobile. Just like that… Again, it is not that surprising: after all, mobile is – by design – the most personal digital medium we have ever had and when this coincides (as it does) with it being the prime access for digital content bar none, you create a very powerful mix indeed. And this will not be constrained to the somewhat crude experiences of feature phone WAP browsers either: in 2011, we will see smartphone penetration breezing past the PC size (desktop and laptops alike). It is mobile, mobile, mobile!
