4 sales in the beginning of 2008 :
fashion.fm $1,809
webradio $345
emma.fm $90
lost.fm $600
So as you can see, there are very few .fm sales but there's a slight increase over the years.
Note that these are only reported sales and I would expect .fm sales to be typically the kind of sales that would remain private.
I also noticed that many good .fm domains are already taken and parked, which means that there are quite a lot of people who like them, especially when you consider the high renewal fee and the low number of reported sales.
Finally I do own a few top .fm domains and they do have a very decent amount of type-in traffic everyday.
nice domains.
I think the market is growing slightly for fm-domains. A great extension for radio broadcasting sites.
I have black.fm since oct. 2006 with daily visits.
The comment earlier about lots of parked pages is not a good sign, it means lots of speculators and no users which is where the money eventually has to come from. When supply is much higher then demand prices plummet.
I still see value in these ccTLD's but the strategy has to be different then with .com,
only the very best premium names are worth having in .fm or .tv
People would do well to develop while sitting on some of these expensive names that may not pay off for a long time if ever.
nice catch
