I've watched this show since season 1 on NBC. I'm glad TLC picked it up a few years ago. I'm enjoying this season and I hope they continue it past this year!

Just heard on the radio this show was picked up by TLC for the summer. It premieres July 23rd with about 8 more celebrities.

i learned so much

AGREE wholeheartedly that this is/was an initeresting AND educational show, TV doesn'thave to be just sex or action to entertain. Wake up NBC!

wI love this show! hy cancel such a great show? I hope another network pick it up? Love this show, I DVR'd it. Pls come back to TV.

i really liked this show it was interesting to watch and cool to see where some celebrities came from and for them to find also i thought it was very interesting about Tim McGraw and ashley Judd i really would like if they can bring back this show

again another show that was diferent--does a show have to be dirty, sexy, or insulting someway--this show was educational- entertaining and we saw anew interesting side of a well known person- it made me wonder about my history=i recorded it to make sure i wouldnt miss an episode

I am extremely disappointed in this cancellation. This was a great show. I was always facinated by the things these people learned about their ancestors. If NBC wants to do better in the ratings, they need to stop cancelling the good shows. They should really reconsider this decision. It was my favorite show.

soooo disappointed! i used to look forward to this show every week,and longed for it to return during the hiatus. my time spent watching nbc is getting less and less.

That's why NBC is always on the bottom of ratings you always cancel the best shows. Please bring back Who Do You Think You Are and put it on one of your other channels. Give shows a chance to get a audience maybe you should get rid of the Nielson Ratings those people apparently don't have taste in shows except the low budget shows.
