The topic of the effects of TV on babies has been discussed many times before on this Forum, for example:

We also have an article written on this topic at BrillBaby:

A lot of the discussion centered around a 1997 University of Washington study done on DVD programs like Baby Einstein and Brainy Baby, with the result of the study summarized as being that for every hour per day spent watching the DVDs, babies learnt six to eight fewer new vocabulary words than babies who had never watched TV.
I recently stumbled upon this article which challenges that study, and which I find a very interesting read:

Here’s an excerpt:
First, the study is small. Although the researchers touted the inclusion of 1,008 children in the study, only 384 children were between the ages of 8 months and 16 months. Only 215 of those engaged in any TV, DVD or video viewing. It’s not clear how many children watched baby DVDs, but the answer is likely fewer than 215.
The number watching for one hour or more per day is likely fewer still. Next, the validity of the raw data is questionable. Data on viewing habits were collected by a telephone poll of parents. The researchers didn’t observe or validate any of the data collected and parents may easily have over- or underestimated their children’s actual viewing habits.
It’s also quite possible the data are biased, potentially skewing study results, since they weren’t collected from a representative sample of the general population. Study subjects were drawn from limited geographic area on the basis of telephone number availability.
Telephoned parents could decline to participate. Moving past the study’s questionable data, the researchers’ technique for measuring child language development also is problematic. While the so-called MacArthur-Bates Communicative Development Inventory, or CDI, seems to be a reliable assessment tool for older toddlers, its application to 8- to 16-month-olds is not so reliable, according to a study published in the journal Child Development (March-April 2000).

These are my thoughts:
Firstly, what we must remember is that the issue isn’t whether TV is ‘bad’, as some people seem to lump it all together. TV is just a medium, just like computers, just like books. What’s key is the CONTENT (even books can be ‘bad’).
On the subject of Baby Einstein, and speaking from my own experience, I felt that most of the DVDs didn’t hold Felicity’s attention, and I didn’t feel they had too much educational content. (One exception I would mention is the multi-language one which I thought was good, and where I ripped out the audio track and played it often to Felicity even when in utero.)
HOWEVER, I didn’t feel that they were ‘bad’ either and I do question myself whether it’s really true that these DVDs could have a direct effect on decreasing a child’s vocabulary.
Of course, I think it must be the case that if we let our child spend a lot of time doing one non-interactive activity like passive TV/DVD watching instead of interacting with that child, then the child’s vocabulary would suffer. But then, that argument would also apply to playpens, ‘solo’ playing in general, or any activity where there isn’t any verbal interaction. Should we frown on playpens and playing too then?
I think the lesson which we SHOULD take from this study is that whatever we do with our children, we should always try our best not let that activity be a substitute to our interacting and spending time with them, or at least to reduce it to as little as practically possible.
I know often it can be very convenient for us busy and tired parents to use the TV (and playpens etc) as a babysitting tool (and I will be the first to put up my hand as someone who has been guilty of having done that!), but we just need to be mindful of it and not let it get out of hand and to reduce it to a bare minumum. And also, if we’re going to use the TV or DVDs, then we should at least try to choose the ones with the most educational value.
