It’s funny that just yesterday I was writing about Google buying YouTube for $1.6 billion dollars. Late yesterday afternoon Google just announced their hefty purchase of DoubleClick for $3.1 billion.

Google revolutionized the web advertising industry as well as the concept of creating successful ad supported free services such as gmail, Google earth, Google maps, google desktop search, and of course the Google.com search engine. One area Google has been targeting is display advertising such as banner ads and video ads. Adsense publishers have always had the option to allow image ads to be displayed on their websites, but, Google’s flagship advertising product has always been text based contextual ads.With

the addition of DoubleClick to the Google family, they will have access to the success that DoubleClick has had in the display ad market. Google’s stock price last traded at $466.29 on Friday. It will be interesting to see which direction it moves at the bell on Monday morning.

After Google boought YouTube in October of 2006, their stock saw a steady increase past the $500 mark. Take a look at this stock chart from late 2006. I’m not saying it will or will not happen again. I’m just saying that the initial public reaction seems good. Things could get interesting next week. I’ll definitely be keeping my TD Ameritrade ticker windows open.
