TNA has cut way back on the number of talents that are flying in for TV tapings, and word is that there have been a lot of signs that the company is worrying about money even more these days. This is because the costs of taping TV have grown due to being on the road, and also because the company hasn't created new revenue streams or improved on the ones that they have. It also doesn't make sense to fly in talents that aren't going to be used.
It should be noted that they are nearly "breaking even" on some TNA iMPACT! tapings on the road so it's not as bad as some are making it out to be.
