The! Biggest! News! of! the! Day! - Katie Couric?

Here are some of the contenders for today's biggest...news...of...the...day...

• The productivity report which showed higher labor costs and spurred chatter of inflation...
• A new CEO for Ford Motor (F)...
• Word that Google (GOOG) will enable searches of historical newspaper archives...
• Some skepticism on investment banks like Goldman Sachs (GS), Lehman Brothers (LEH) and Bear Stearns (BSC)...
• An SEC filing from Hewlett-Packard (HPQ) related to a "leak probe"...

While those are all stories worth watching, I think it is obviously clear that the biggest story is of course Katie Couric's debut which will be the entire focus of today's blog...just kidding...
