Coca-Cola has brought caffeine drink Surge back, exclusively on Amazon. The first batch sold out within hours. The drink, which started as a Norwegian Mountain Dew competitor in 1996, was off the market by 2002. Coca-Cola says Surge is a limited rerun, though that may change that if the drink's popularity stays high. Coca-Cola says a Facebook page, Surge Movement, was the impetus for the company to do the relaunch.
