I no longer watch much TV let alone CNBC. However, when I am not RV'ing or up in my 2nd home, I tend to spend quite a bit of time on the Web. I also listen to no radio, so the Web is my window into the world for everything. I have also cancelled all of my printed subscriptions. I guess I spend a few hours each day on the Web, except when I have no access (and that's often by choice).
Time spent on the Web is for surfing this forum but also to BS and not just to glean some tidbits of financial wisdom. I also use the Web to get info from news media, but that's to follow political news and macroeconomic trends, not really for stock info.
Though I have quite a few individual stocks, I buy with the intention of holding for long terms. I have no spreadsheets. I relied on MS Money, and now Quicken for performance tracking. If a stock suddenly deviated significantly from the pack, I would investigate then decide what to do about it. Else, I would let it be and only look at the longer term performance. I do look at my Quicken screen several times a day. I need to look at Quicken for expense and credit card tracking also.
