Did we learn anything from the last two weeks of omnipresent Olympics coverage? Well, yeah. We did. Thanks especially to NBC and its cable networks, streaming feeds and not-quite-ready-for-prime-time measuring systems. Last week, I mused about the next 20 years in media -- that is, the broader media eco-system and what it might look like in the next couple of decades. Live and learn, I posited. This next decade will definitely be one of near chaos as media companies -- all sorts of them -- try new things, try to resurrect old things and pray that change doesn’t happen so fast it doesn’t run over them. Just think of what happened to long distance telephony. So … back to NBC. So what did the peacock accomplish besides lower TV ratings? Well, considering those changes that we’re all trying to outrun, quite a lot.
