Shop on Twitter with a hashtag

-It's time to go on a Twitter shopping spree. I'm Bridget Carey and this is your CNET update. The social media giants are finding new ways to get you to spend money. First off, Facebook is rolling out a buy tickets option, so it's easy for you to buy tickets to an event right on Facebook. It's gonna be an option for all event page owners and the buttons will take you to a third-party website. Right now, there's not much to the button except that it's a new way to get your attention. Facebook is taking baby steps as it does more and more with commerce. Twitter is also experimenting with shopping. Twitter has a new partnership with American Express. It lets cardholders make certain purchases just by tweeting a special hashtag. First, users have to add Twitter info to their AmEx card account then the American Express Twitter account will tweet out these discount deals. And if you want one of them, you have to reply with a special hashtag. American Express then sends a reply back with a confirming hashtag. And if you confirm, within 15 minutes, the transaction is complete and the item is mailed to the address on file. Of course, even though you'll be getting something on sale, you'll be telling the whole world what you're purchasing, so I hope you don't mind giving up your privacy or hope the person you're giving a gift for doesn't use Twitter. So, Apple's CEO Tim Cook, he is really not a fan of OLED displays. While Cook was speaking at an investor conference, he said the color saturation of OLED displays were "awful." Yeah, he didn't hold back on that one. He added that you just can't trust the color accuracy of OLED. Of course, Apple's biggest rival, Samsung, uses OLED in the latest Galaxy smartphones. Cook went on to say that he doesn't want to get into a battle over size of screens or prices, but rather experiences like the quality of the display. And in home theater news, an Intel executive confirmed that Intel will be unveiling an internet-based TV service and box later this year. Intel will provide the hardware and the services direct to consumers. And this box will have a camera to detect who is in front of the TV. So, we'll have to keep an eye out for that. We've seen plenty of apps that share short video clips, but there's a new one that's doing audio. Talkbits is like a Twitter for people who wanna talk instead of type. Your message is limited to 15 seconds and you have that voice message shared into a channel. Channels are themed around different locations, so you can be given a message about what's going on in your city, town, or ask a question to locals about places to visit. It's free and available for iOS and android, but it's still very new. So, it will take sometime to build a network of engaged users. For now, you could just have fun making shout outs to the early adapters or maybe you can describe your lunch to this guy. That's your tech news update.
