Here’s a good sign-of-the-times story by the L.A. Times Josh Friedman about online sports-betting sites taking in some fairly decent coin each weekend from taking bets on Hollywood box-office . “By putting their money where their entertainment hunches are, [betting-minded moviegoers] are turning the weekend box-office derby — once followed mainly by studio executives and accountants — into a participatory sport,” Friedman writes. “Online entertainment betting, originally a novelty aimed at hyping the sports books during Oscar season, is on the rise. World Sports Exchange, which runs a gambling site at wsex.com, reports that its movie wagering volume jumped 26% last year. These days, the site takes $25,000 to $50,000 worth of bets on each weekend’s box-office results.”
