Bloomberg.com: McDonald's Corp.'s $1 menu offers more than burgers, chicken nuggets and fries. Diners can now rent DVDs from automated kiosks for a buck, $3 cheaper than at Blockbuster stores. Blockbuster, the largest video chain, and Netflix, the biggest U.S. mail-order movie service, are losing sales to discount kiosks in an overall market that hasn't grown since 2001, says Adams Media Research. Adams estimates Blockbuster has 39.2 percent of the U.S. rental market, including franchised outlets.
