Looking at Twitter of late, it seems that most of the posts are sponsored. Makes it hard to follow the game publishers posts. The current volume of ads makes Twitter almost useless.
Facebook has also make a mess with ads. It seems that along with Twitter, social media has become a mess with the excesses of capitalism.
Here at studio the same old ads that have been in place now for over 5 years. The ad is supposed to be contextual but much of the time it does not work at all. The old ad tools are obsolete as specific products have such a short life in the market before it is replaced with different models.
The is not much motivation to change the ads. That are designed for long term placement.
