AMC’s "Breaking Bad" was the big winner at the Emmy’s this week, taking home the award for best drama series. It was the second straight win for the dark tale of Bryan Cranston’s chemistry-teacher-turned-meth-kingpin Walter White. Meanwhile, Amazon.com said Tuesday it is buying Twitch Interactive for $970 million in cash. Twitch is an online network for people who not only enjoy playing video games, but like watching others play as well. Twitch had 55 million unique visitors in July, up from 20 million in 2012. Finally, shares of Kite Pharma jumped over 20% to more than $26 this week after the biotech announced 12 out of 13 patients in a clinical trial showed some form of remission in their Non-Hodgkin’s Lymphoma after receiving the company’s drug candidate KTE-C19.
