Based upon average daily viewing time of 6 1/2 hours, Panasonic 1080p Plasma HDTVs could on average take more than 42 years before they reach half of their original brightness level.


Sure, and if you swallow my load, I'll swallow yours.

That's great - we can now all enjoy burnt in dogs/logos at full brightness for the next 42 years.

Ok, I'll translate:

Based on looking a random material, a Panasonic plasma will reach half brightness at 100,000 hours.

OK, that means that looking at part of a logo, bug, or banner at full brightness, they will, at best, fall to half brightness in about 20,000 hours (because they are probably assuming an 18% gray average).

Assuming a linear fate of burn, that means that you will get a very visible

5% burn difference between a bright bug and black bars in 1/10 of 20,000 hours or 2000 hours. That sounds about right for a type of set that has known burn-in problems.
