Girls show off their purchases online, become YouTube stars and even attract sponsorship. The power of these "consumer reviews" by a group with tremendous retail purchasing power and influence is undeniable.
ABC News reported there to be about 110,000 haul videos currently on YouTube. Originally displaying predominantly cosmetic purchases, this has expanded to include anything from bags to shoes to clothing for their favourite pet - commenting on the quality or the purchase as they vlog along.
Even more powerful than peer reviews and like buttons, it is anticipated that marketers will be hot on the trail of this technique, canvassing user-promoters that are happy to promote their products - a second-cousin technique to mystery shopping.
