You should take a look at the research - there is established evidence for the impact of television on language development. The book NurtureShock gives a nice overview, but if you want to go directly to the research papers it looks like there are plenty of papers like this:

The problem with TV in particular seems to be the lack of interactivity. Children learn best by getting meaningful feedback from other people, and television cannot provide that. iPad apps and computers should be able to overcome that limitation, but I think we're early in the process of understanding the most effective ways to provide that for children, especially young children.

Thanks. That particular example is about children under two years. Do you have anything for older children? Under two years falls in my category of being neurologically unprepared to deal with the stimuli from TV. But what about at 4, or 6? The children are in a very different development stage, and (from my current, but always adapting, perspective) it becomes a balance of negatives and positives. For example, I have seen how TV accelerates understanding of social situations --- it is like having exercises at the end of a calculus chapter, but for preparing for the variety of social situations one will encounter, and learning to account for someone else's perspective.
