I'm sorry but this is groundless and can be proved wrong very easily.
Let's compare the recent sales of .tv and tv.com domains.
For this comparison, I'll be using domain sales data as provided by Namebio.com since the beginning of March 2008 (that would be fair to study recent sales in the current market).
tv.com domains : 17 domains sold
5 highest sales since March 2008
hotgirlstv.com $1,200
cleantv.com $1,100
health-tv.com $1,020
sauditv.com $1,002
discovermetv.com $1,000
.tv : 105 domains sold
5 highest sales since March 2008
fussball.tv $28,367
viajar.tv $12,647
it.tv $12,500
welcome.tv $10,000
ntv.tv $5,680
As you can see, there have been recently far more .tv sales than tv.com ones, and these sales have generally been much higher.
Despite what some people say, .tv domains have already won the battle against tv.com. and the gap will keep getting wider and wider in the years to come, as more and more Internet users get aware of this extension and more and more businesses develop and promote videocentric sites.
