Uh-o, somebody just blew the whistle. You know how you were spending your lunch hour (or however many minutes you can get away with while eating your tuna fish sandwich) in your office cubicle catching up on that episode of Ugly Betty or Grey's Anatomy you missed? Well, you're not alone. Nielsen Online has measured Internet traffic and just released data that indicates that peak viewing time is weekdays between noon and 2:00 p.m. Moreover, the number of people watching TV episodes online during these lunchtime hours is 50% higher than the average of all other times.
