On the other hand, once all of the legal challenges are out of the way, I can't imagine there won't be a bunch of other companies swooping in to undercut them. $500/month for a service like this? I'm thinking that has the potential to go down significantly and quickly, with competition.
For instance, I can imagine a cut-rate service that doesn't do speech-to-text but instead relies solely on closed captioning. Or a plan that monitors only a limited subset of channels. It might not have all the features of TVEyes, but may have enough to hurt TVEyes' business if it doesn't lower prices and offer a limited tier itself.
It might not make sense for such a service to pop up now, while the legal issues are unsettled, but if TVEyes bears the litigation burden to get those issues settled, I can't imagine it wouldn't face stiffer competition down the line.
