ATD on the TV: Toasty Twitter, Amber Alerts, Dell and the NFL

This week members of the AllThingsD staff showed up live and in person on all sorts of channels. Should you want to see some of the week’s tech news highlights, rather than just read about them, watch these quick videos.

Mike Isaac turned up on CNBC with some smart answers to a somewhat silly question: “Is Twitter toast?”

Arik Hesseldahl joined WCBS to give some background on emergency cell phone alerts, after one woke up many New Yorkers in the middle of the night.

He was also on the BBC for a hit on the ongoing Dell saga, which he’s been covering on a more-than-daily basis.

And then our media guy Peter Kafka showed up a couple places to talk about a theory that Google or Apple might gain a foothold in TV by buying online broadcast rights for football. Here’s Peter on the Wall Street Journal’s Digits show, and Bloomberg’s audio podcast “The Inside Scoop.”
