CNBC losing lots of viewers

July numbers were down in every hour block from 3 a.m. to 4 p.m., according to Nielsen, with the biggest overall drop for "Mad Money" with Jim Cramer. They're also tuning out CNBC's "Closing Bell" with Maria Bartiromo in droves. Overall the network saw an 8 percent decline in viewers year-over-year. StreetInsider.com.speculates that Fox Business Network could be gaining some traction. But perhaps there's another factor at play: Investor distrust of the market. When folks have so much of their money on the sidelines, there's not much need for CNBC.
