I'm a product of the 80's so I loved MTV, back when it was MUSIC television. Then the garbage came along; "reality" TV (which is anything but reality), etc.
MTV was a victim of it's own success. It brought a new concept forth; a desirable product melded into a dedicated media. And then it became irrelevant due to personal video-based tools like cell phones and laptops. While music itself survives, the "fad" of seeing music videos has died off. YouTube and other services do much more, offer broader content, offer personalize searches, etc. MTV should have been killed off two decades ago; no one has had the decency to properly cull the tired old beast.
Same goes for satelite radio and TV (I subscribe to SXM, at least for now ....). But it see it as a dying breed. It's too easy to just stream IHR, Pandora, etc on a device you already pay for. Paying for a satelite service is just redundant spending. Direct TV is also dying off; owned by ATT. They are desparate to keep it alive, but it's too easy to pay for other streaming services and get more personalized products you actually want.
I've been enjoying SXM's retro look back into the MTV haydays; several of the old VJs are now on SXM.
