They did a very good job in the 1990s for a while when the commemorative stamps came out, re-releasing the core films on VHS and securing tie-ins with Pepsico products (soft drinks and Doritos). Things like that help; I'm not sure if they're cost-benefit effective in the long run.

Honestly, Blu-Ray box set was a heck of a step, but I didn't see much mainstream media coverage or adspace. Was I just living in a cave? (I do that often.)

I play it cool
And dig all jive
That's the reason
I stay alive
My motto
As I live and learn
Is:
Dig And Be Dug
In Return.
