Yep, in season 2 John Ross has an unbranded black Lumia 920. His new wife Pamela Rebecca uses a Surface too. A lot of Microsoft influence in the new Dallas, especially being MS has commercials on every single break.
On the show Nashville, Hayden Panettiere's assistant is always carrying around a Surface with a red cover, while there was an episode of Hayden herself using a Surface with a blue cover with her boyfriend. There have also been various spottings of Lumias in the show as well.
You guys realize that Microsoft was a big sponsor of a lot of CW shows. Most of which you guys mentioned in this thread. You'll also see a TON of the Surface on 90210.
