The industry is definitely shifting. Some of it on their own doing, some of it forced on them by a ton of external forces ranging from reality TV to Tivo.
Interesting that the article mentioned the Upfronts. Those actually may be a thing of the past soon, too.
The network I work for told us we would be doing them this year, but gave us not so subtle hints that this might be the last. After that, we'd likely pitch to our advertisers in smaller, more personal settings.
There's no question a year-round lineup makes the most sense. It'll be more trying on the networks themselves, but should lead to increased revenues.
I'm fine with it. It'll keep us working more, and I believe ultimately lead to better programming choices for people.
TV really is going to change. The next decade will be very interesting.
