In 2006 a start-up called StarStyles tried to sell products, one could see on TV immediately, see article here.
According to CNET, Google now bought into Pixazza, a start-up linking photos on the Web with sites where people can buy the products in the images.
The company is now launching the technology for general use by advertisers, Web publishers, and the network of self-appointed but screened specialists who identify the products in the photos, said Chief Executive Bob Lisbonne. The company is starting with the apparel industry but plans to expand to home design and furnishings, travel, electronics, and sports starting later this year, he said.
StarStyles does not exist anymore. All though many Top brands joined early and plenty of big retailers collaborated.
Maybe TV consumers were not interactive enough?
If Pixazza works, product placement will get a push and will be more meassurable.
