A website called 24/7 Wall Street just released a list of major companies that are in SERIOUS trouble . . . meaning they'll be sold, bankrupt, or completely EXTINCT by the end of 2011.  Here are some of companies that may not exist in 18 months:

#1.)  ZALES JEWELERS.  The value of Zale Corp. has dropped from $1.3 BILLION in 1999 to $78 MILLION today.

#2.)  READER'S DIGEST.  Circulation is WAY down and the company's U.S. branch has already had to declare bankruptcy once.

#3.)  BLOCKBUSTER.  Netflix, Redbox, and On-Demand are killing their stores.  They may live on by copying those companies, but the stores could all disappear.

#4.)  DOLLAR THRIFTY RENTAL CARS.  There are six major rental car brands, and not enough demand to support all of them.  And this one's the most likely to go.

#5.)  T-MOBILE.  It's the number four cell phone provider in the U.S.  They'll probably have to merge with another company like Nextel did with Sprint.

#6.)  BP.  Obviously . . .

#7.)  RADIOSHACK.  It looks like they'll either get taken over by Best Buy or just disappear completely.

#8.)  KIA MOTORS.  Hyundai owns Kia, and they'll probably just get rid of it.  It's a weaker brand name than Hyundai, and there's really no reason for them to keep it alive.
