Well they do but the announcement was made via ustream at this afternoon's news conference. I linked the video and some pictures I saved during the conference on my website (http://geekslop.com/2012/nasa-finds-evidence-of-flowing-streams-on-mars). I felt like they played it up a bit but I guess I buy their reasoning.

Lots of utilities are rolling them out right now and big companies who want to keep an eye on their usage patterns demand them. Remember when they used to hand read meters? The guy would open the gate, dodge your barking dog, and write down the meter reading in his little book. Then they moved some to radio transmitting meters where a utility truck simply drove down your street and recorded the readings that were transmitted from each meter. Now they have meters that communicate wirelessly and send the readings to the utility company in at intervals.
