This problem is extremely rare on LCD, typically indicates a faulty design (excessive overdriving) and image retention is usually non-permanent, since every time you switch off the display, it "resets" the pixel wear.
For people who use an LCD even 8-12 hours a day, as long as it is switched off for the rest of the time, it should be very rare that you see image retention, and permanent damage is almost impossible.
With Plasma and OLED, wear accumulates over time and it is very possible for wear to occur through "normal" usage e.g. watching television channels with logos, 4:3 or 21:9 content, playing video games, using a computer connected to the display etc.
While CRTs used to be susceptible to burn-in, it was almost impossible through normal home use in the later models, and would really only be seen on displays which were used for things like arcade monitors or airport displays, displaying static content for every moment that they were in use.

It probably depends on how much of a gamer you are, and how much you vary the content that you watch.
If you play games for an hour and then spend the next four hours watching broadcast TV with 16:9 content that doesn't have any channel logos, you are unlikely to ever have a problem.
If you're the kind of person that gets home from work and plays the same game for several hours each day while watching very little other content, or someone that spends most of their time watching films on Blu-ray, it's going to be a real problem.
Personally, I only watch films (mostly letterboxed) play games, and use a computer hooked up to my TV, so almost everything I use the display for has static content.
I don't watch any broadcast content, so the majority of 16:9 content I use has a lot of static elements. (Games/PC)
When I get invested in a game, I tend to play it to the exclusion of all other content. Films or TV shows (I do buy a few shows on Blu-ray) take a backseat to the game.
It's not like I have a schedule to keep where X show is on at 9pm and I "have" to watch it, which "forces" a break from the game.
I don't mean to suggest that I have a problem, but if I have three hours spare in the evening, I'd rather spend it all on whatever the latest game I'm hooked on is, than spend it watching three hours of TV. (45 minutes of which is advertising)
