Considering the latest Forrester Research study about online advertising the future is bright for the 21st century’s media giants, like Yahoo! or Google, and here are some excerpts from this study:

• 2005 growth in online advertising spending, represents a 23 percent increase from 2004, up to $14.7 billion and it’s estimated to $26 billion by 2010

• This is not the return of “The Bubble”. The growth is coming from marketers having to make tough decisions about allocating scarce advertising dollars – in many cases, funding online channels from traditional channels. Back in 1999/2000, spending often came from exuberant spending, fueled by venture money.

• It’s more than just about search. Search is great, it’s growing, but it’s not the whole story. In fact, I anticipate that search will become much more integrated into traditional brand advertising

• Marketers will shift channels away from traditional channels to fund online marketing

With all these in mind, Fortune Magazine, published and interesting article on Yahoo’s Brilliant Solution, an in-depth analysis on Yahoo’s approach towards winning more and more of the online branding advertising dollars.

And in the scrum for online brand advertising—almost as large a market—Yahoo is poised to grab the biggest share. Its 181 million active registered users are probably the largest online clientele, which means Yahoo can tell advertisers it knows the habits of more users than any other portal—or any traditional media company.
