It's the opinion of Netflix execs, who have expressed envy over how much money HBO is still making off of decades old IP. Not a lot of Netflix content has legs like that, but I suppose that's about to change with the WB acquisition.

I'd say Disney is the uncontested king of making money off old work. If HBO was that good they wouldn't have been scooped up so easily.

Netflix execs may be envious of the enduring cultural cachet of shows like The Sopranos or The Wire. That's completely different from making real money.
