I totally missed the replacement of the crawl, but one of my favorite TV blogs is all over it!
I also never understood the point of the crawl - on the financial nets, it was nice to see the stock prices scrolling by, so it made sense there. But why did the news nets decide it was a good idea to distract their viewers instead of just giving them the news? Have we as a culture become so attention-deficient that we can't watch 30 minutes of straight news without video game gimmicks to keep us interested?
