I think Marathoning was officially renamed "watching TV" when Netflix starting putting 7-10 seasons of shows up at a time. I pretty much picked a series and it became background noise while I messed with around with graphics programs or some inane project for 12 hours on a saturday. I'm pretty sure me and my wife killed like 40 or 50 complete seasons of different shows in a matter of a month or two when we first got Netflix.
