Why is DVI not more prevalent?

Stopped into Wally World last night and all they had was HDMI and VGA... Talk about separate ends of the spectrum. I feel that DVI is almost a staple on all monitors/graphics cards/motherboards, so why would you only stock VGA and HDMI? HDMI is not an input on a lot of monitors and VGA is slowly, but surely disappearing. My opinion, but I also haven't bought a monitor in the very recent future.

DVI costs money to use, like $1 per usage, where as HDMI costs a few pennies. Scale that by millions and it's someones decision to say, lets save $10,000,000 by only putting HDMI and if they only have DVI, they can buy an adapter.

Ok now I'm really interested, how does it cost dollars to use, let alone money at all? I get that you buy the cord, or the power put into it, but I'm not sure I understand exactly what you mean?

If you want to include DVI, you have to pay a licensing fee to the DVI federation or whatever they are called. These groups that create standards, some charge for them on a per usage basis. DVI, HDMI, Dolby, Bluray, Prologic, all these things costs the makers to actually have the right to make a device that supports the technology.

I'm pretty sure HDMI has far more royalties than DVI. Can't find anything on DVI royalties. DP says it is royalty-free.

DVI is a larger connector, and has been superseded by DP. You won't find it on a typical laptop or even consumer desktop, so it's really only in use in enterprise or gamers.

HDMI is just as capable as DVI (when the display is correctly programmed), and supported by everyone's laptops and TVs. VGA is supported by everything, so is a lowest common denominator for when you have a projector or something in a classroom/meeting room.

So if DVI is really not that prevalent, why is it on almost all monitors?
Which is a better connection DP vs. HDMI vs. DVI? (I am leaving out VGA as it's analog, but I guess it's possible it could be as fast) In terms of gaming (mostly care about response time), enthusiast (mostly care about color correctness and fastness aka how long it will stay that way), and maybe the average joe (just wants it to look good).

Because it was prevalent (and for a while was the only way to get high resolutions). Same reason many motherboards still have PS/2 ports.

HDMI is almost identical to DVI, I believe.

I'm pretty sure they're all close enough that it's impossible to tell the difference.
