Back in the late 90’s I started noticing URLs at the end of many TV advertisements. They started as general company URLs (and were relatively infrequent) and eventually because almost ubiquitous leading not just to company home pages but eventually to product pages or other ares of a company’s site were one could get more information about whatever was being hocked on TV (or in a magazine, etc.). Fast forward a few years and we saw the same phenomenon with brands and their Facebook pages. And then Twitter. These were/are great ways for brands to get more information to people interested in their products. And to some extent through Twitter and Facebook “engage” with people so inclined to interact in that way…
