Online advertising is a viable business

The head of Goldman Sachs' high-tech group has said that the IPO market is back for the right Internet companies. However the barriers are far higher, and we're not likely to return to unprofitable or no-revenue companies getting piles of investors. Now that advertising is a viable business model, with further strong gains in online advertising dollars likely, many more online businesses can flourish, or at least fight for the advertising dollars available. On a related note, a group of prominent bloggers have united to create a blog aggregation site, which will compete with mainstream media and live on advertising revenue. They may not make a fortune, but just around now this has become a viable business model.
