REALITY Big Brother CBS, Global, 9 p.m. ET/PT Back tonight for its 14 th season, this series received advance publicity when CBS attempted to file a lawsuit against ABC for launching the copycat series Glass House (the lawsuit was thrown out). As before, the concept features 12 complete strangers sharing a house outfitted with cameras and microphones recording their every move. One gets voted off each week and the last one standing collects $500,000 (U.S.). In a slight format tweak, the house will also open its doors to four previous Big Brother players, to be named in tonight’s opener, who will compete for a separate prize. Once again, the core group will run the gamut of American life – a goth girl, a chef, a trucker, a waitress and so forth. And if you’re really into the series, you can watch them 24 hours a day on the show’s website.
