It is hard to imagine the original NBC Studio Tour, started in 1933, offering so much of so little, as does the current "NBC Experience" tour. It seems as if NBC has kept busy these last seventy years collecting scads of tacky television glitz with which to pad this new, thin experience.

The guided tour starts at the NBC History Theater where a Page lightly touches on NBC's early radio background. Then there is a retrospective/public-relations video hosted by Matt Lauer and Katie Couric. No surprise. You wouldn't be here if you didn't enjoy watching TV.

Next it's on to the stages, shooting-schedules permitting. You may visit anywhere from two to four stages, the homes of shows like Saturday Night Live, Late Night with Conan O'Brien, Dateline and NBC Nightly News. The stages, mostly empty during down times, are surprisingly small and gloomy without their hosts, and definitely seem to lose some relevance.
