how will cnbc viewing affect baby development?

Even at 8 weeks, I see my son recognizing the television as he would another person in the room speaking (As I type, Go Diego Go! is buying me 15 minutes to the next feeding). The TV isn't on all day, but I have to wonder how my news-phile tendencies will affect my son's little brain.  Will my son trend toward finance? Will exposure repel him? Will it matter? Will he be irreparably scarred after a Jim Cramer segment?

There have been reports of passive TV watching being harmful to attention spans, but at what age? My older child, now 12 yrs old, started to show behavioral issues by age 2 from too much tv, to which we promptly cut tv time down to 1 hr a day from 2 hrs, but is there anything out on infants and benefits/detriments of tv? If so, doesn't that include the oh so hyped Baby Einstein series?  We tried to sit thru a Baby Einstein video and while my son was somewhat engaged, how do parents survive them?
