As NBC readies to conduct its upfront presentation today, it has done what every other prime time network has had to do and has cancelled its under performing shows. This year NBC will be cancelling a total of 10 series which is one less than ABC. Surprising for many, two shows; Revolution and Community were both cancelled and its looking like neither show will find a new home on any other network. Unlike other networks the genre that was hit the hardest for NBC was its dramas, this year they will be cancelling 6 of their dramas most of which were in there freshman seasons. So grab a tissue and check and see if your favorite show will not be returning.
