Cambridge Investments - Open for Public Registration (Fairfield, Iowa) -- June 5
Lean Healthcare Transformation Summit (Chicago) -- June 13

The headlines I saw had a lot of two-data-point comparisons. Headlines sometimes gave the percentage decrease in viewers or how many million fewer viewers there were. Many talked about "record low" but if you're tracking a metric "record low" or "all-time high" doesn't mean there's a "special cause." That "record low" could still be noise in the system.
