So Day 1 of ad|tech (New York) is almost over. My initial impression is there's an awful lot of bullishness and enthusiasm about the online advertising market. ad|tech's Drew Ianni kicked off the three-day event by talking about the market getting to $20-billion in short order, and how there appears to be a shortage of quality inventory (aka good places on the Web for companies to place advertising). Judging by the number of people attending the conference and the number of exhibitors, the online advertising business is extremely healthy. By "business", I mean companies such as ad agencies, Web sites/networks and technology/service providers. On the other hand, advertisers - the ones spending the money - continue to be cautious, pragmatic and still in need of more education/hand-holding before they commit more of their budgets to online vehicles. One of the highlights was a session on user-generated content featuring Ze Frank. With his current "project" slated to end in March after a one-year run, Ze is apparently working on a "secret RSS" project. He also talked being interested in micro online communities with about 1,000 users. Tags: , ,
