Creating substance-free shows because you think your audience has no attention span is a sucker’s game. And streaming shows for free is, so far, doing a lot more for viewers than it is for a network’s balance sheet. Instead, the networks should try to make TV shows for people who want to watch TV shows. There seems to be no shortage of viewers out there: For all the hand-wringing about how new media are sapping television’s audience, the average viewer of online video in April watched fewer than eight minutes a day. By contrast, the average household has its TV on for eight hours and 14 minutes daily. That’s a record. (One that should make all of us rear back in horror, but that’s another story.)

5. When you say the TV season is 52 weeks, you have to mean it.

Madison Avenue is still fond of the old-fashioned idea of fall as a launchpad for a new TV season, and so are many viewers. But does that mean the networks should continue taking summers off? Sure, they run original programming in July and August, but “original” in this context generally means a series so odd that they couldn’t find a place for it in the regular season, or Celebrity Circus, or 85 variations on foreign game shows (this summer’s flavor of the moment).

It’s a bind, since a real commitment to top-quality original programming during the summer costs money that the broadcast networks don’t have right now, but a diet of reruns and cut-rate schlock may cost them viewers. According to Comcast’s Harbert, when broadcast execs ask for new shows year-round, “the finance guys say, ‘You’re killing me!’ And the programming guys say, ‘Yeah, but if I put on repeats, they’re going to have terrible ratings, and we’ll have no promo base for fall.’ And everybody’s right.”

But investing in shows—and thus in audience building—is a smarter long-term strategy. It’s no accident that cable hits like Lifetime’s Army Wives, USA’s Burn Notice, and TNT’s The Closer all launched in summer, allowing cable to perform its annual raid on broadcast viewers.

6. Don’t break faith with your audience.

Broadcast networks routinely spend three months promoting a show that they then cancel after two airings. Or they get a few million viewers hooked on a serialized drama and then drop it midway through a season, leaving fans hanging. This simply never happens on cable, where if a series gets a 13-episode order, those 13 episodes are damn well going to air, even if it’s just because there’s nothing else to take their place. Every time the networks reshuffle their grid in a spasm of quick-fix panic, they disenchant more viewers.

7. If you can’t beat ’em, eat ’em.

Ben Silverman, NBC’s head programmer, may fret when one of his network’s shows struggles against a basic-cable hit like Bravo’s Top Chef or the Sci Fi Channel’s Battlestar Galactica. But his boss, NBC Universal C.E.O. Jeff Zucker, will rest easy, because his company also owns Bravo. And the Sci Fi Channel. And a whole lot more. The notion that the “500-channel universe” is a pie being cut into ever-tinier slivers ignores the fact that the vast majority of what we watch fills the coffers of a small handful of megaliths, just as it always has.

Take a closer look at that pie:

• Besides Bravo and Sci Fi, NBC Universal also owns USA, the highest-rated ad-supported cable channel; MSNBC; CNBC; ShopNBC; Oxygen; Telemundo; and one-third of A&E Television, itself a conglomeration that includes A&E, the History Channel, and the Biography Channel.

• Disney owns ABC, ESPN, SoapNet, ABC Family, its own one-third share of A&E, and half of Lifetime. It also, of course, owns the Disney Channel, the top-rated basic-cable outlet of any kind.

• Viacom and CBS, though now traded separately on Wall Street, are both controlled by one man, Sumner Redstone. CBS owns Showtime, the Movie Channel, and half of the CW. Viacom’s list of properties includes MTV, VH1, Nickelodeon, Spike TV, BET, and Comedy Central.
