The TV-show theme song: dead and buried?

First it was original movie soundtracks, now it’s TV-show theme songs that are getting an official belated Internet eulogy. The writer laments a world in which “modern TV producers fear flip-happy viewers” and cater to them by launching right into the plot with little or no musical opening. My guess is the writer doesn’t get HBO, because Oz, Deadwood, The Wire, The Sopranos and Entourage all have distinct theme songs that covered their opening credits (The Wire and Entourage are still active shows, as far as I know), as does Law & Order, a show popular enough to warrant its own channel.
