I spent many years in at Hollywood Video corporate in the late 2000s and saw much of it first hand. Blockbuster didn't understand what was going on and Hollywood was too busy trying to copy Blockbuster. Neither of them saw Netflix as a threat until it was too late.
Just as the article mentions, the VCR revolutionized the viewing experience for Boomers who were used to waiting for something to come on TV. The video chains experienced insane success, and thought they could ride that formula out for decades.
Netflix revolutionized movie entertainment for Gen-X and millennials who were used to and unimpressed by VHS/DVD rental models. The execs at the top (boomers) ignored the new fangled streaming stuff because they didn't use it, didn't understand it, and most of all didn't see the value.
The younger of us working at Hollywood saw the writing on the wall in the early 2000s as Netflix was making it's climb. The even younger folks working at the stores knew it even better. But none of us could convince anyone at the top that it was important, until the late 2000s when they made a half assed attempt to be an "also does" to the then dominant Netflix.
When you're in a fast moving business, you don't bet everything on what's happening now, you've got to think about what's coming soon...
