Here’s what Mark Cuban had to say about Netflix this week, in a response to a Web site about the future of TV. (The rest of what he wrote is very much worth the read. Mark Cuban knows a little something about the television industry.)

“Why would the content owners continue to license the content to Netflix for peanuts and put at risk BILLIONS of dollars? Right now Netflix has been BRILLIANT at monetizing previously unmonetizable content. But as the balance of revenues change, so could their access. They already had to give up a 28-day window on movies. You don’t think that is their last concession, do you? The other thing to note is the percentage of Netflix subscribers that already subscribe to a TV provider. Netflix has to be concerned that it will be easier for those people to give up Netflix if their TV provider expands their offerings and allows for queuing of streams to a TV channel than it will to give up the TV provider.”

Blockbuster is said to be closing nearly 1,000 stores around the U.S. as a direct result of the success Netflix is having.

But Cuban says Netflix will hit a ceiling because it is a secondary provider, a compliment to the services provided by cable and satellite companies, which are the primary providers.

He’s 100 percent right: We’ve already seen it happen with TiVo, which ruled the DVR landscape until cable companies figured out how to do it. Not do it better, but just to do it. Cable DVR service is still greatly inferior to TiVo. But it’s more convenient and more affordable to get digital video recording through the cable company, so people do that.

All they had to do was offer DVR service, and cable companies beat the best (and, really, the only other) DVR company doing it. They did it to TiVo, and they can do it to Netflix.
