The TVGoods website with CEO Kevin Harrington. Direct-response marketer TVGoods, fresh off last week’s acquisition of direct-response megasite AsSeenonTV.com, is partnering with Delivery Agent to launch a system that later this year will let people in 20 million U.S. households buy products pitched on infomercials with a click of their TV remotes, without having to head to their computers or deal with telephone operators standing by. In some cases, they’ll also be able to buy stuff they see on regular programming — say the sweater a character on a TV show is wearing — the same way as when they get a pitch to do so via ads overlaid on the bottom third of their screens.
