I just read a brief piece in LA Times Business how twitter is deploying some of its upcoming real-time ads this week.
It's an interesting concept, when you search for things a contextual ad will appear at the top. Interaction with the Ad will control its life span.
Twitter is definitely an opinion charged platform. This can probably be good or bad to advertising.
Try a search for "united airlines".
Yipes, I don't think UAL is going to be buying that keyword and im pretty certain that they don't want interaction to keep it around.
Maybe Frontier will buy "United Airlines". Let's see what a search for "Frontier Airlines" gives us.
Interesting. You can say the same problem exists with Google's business model, but clearly they figured that out. I think the difference is that with Twitter you tend to get a punch in the face, rather than a lengthy piece of content you need to sort through.
Seems like it might work for "loved brands", Nike, Coke, etc. It's hard to get a real visceral reaction to Coke.
Not sure about others.
