Several friends told me that Letter Factory had taught the alphabet and its sounds to their children. I was skeptical, but I got uit and my kids LOVE it! My 3 year old already knows all of the letters that she had been previously struggling with (probably 10 or so) just from watching this video for a week. The story is cute, and if my kids regularly watching videos they may as well be watching something educationally helpful like this!
We will definitely try Word Factory next.
