Has Arbitron really exited the streaming audio measurement biz?

Katy Bachman, in a brief article in MediaWeek reporting on the decision by TargetSpot to use AndoMedia for its streaming audio measurement, also stated that:

Arbitron quietly decided to get out of the streaming radio ratings business earlier this year and discontinued its relationship with comScore. According to industry sources, Arbitron was unable to make money from the business faced with a competitor who charged little or nothing for the ratings and delivered them as a byproduct of its ad server business.


Well, it must have been very quiet, because the only other mention of this I found was on the blog Internetradioworld in a post on April 9th:

According to industry sources, Arbitron was unable to make money from the business faced with Ando Media, their main competitor, who charged little or nothing for the ratings and delivered them as a byproduct of its ad server business.


InternetRadioWorld's blog entry seems to be an analysis of the impact of such an exit on the industry.

Both of these articles were within days of Arbitron and Edison's announcement of the research from their "Infinite Dial 2009" survey indicating that online radio listening cume audience has increased to 42 Million.

Now - Michael Skarzynski, the new CEO at Arbitron, and all the other folks at Arbitron, are pretty smart. I strongly doubt that Arbitron is "getting out" the streaming audio measurement business and leaving it to AndoMedia. And the folks at ComScore are quite bright, too. Measurement of streaming media has been a big investment for them and the market for this data is only going to grow. So, what's up here?
