I would like to see the competition between Quattro and AdMob under the tutelage of two well-financed companies -- Google and Apple. Here Google has a greater market share already, i.e., where it could port AdMob ads. My concern for Apple is that it is pricing its ads too high so that only a very elite group of companies could afford them. Also, advertising revenue is very sensitive to the health of the economy. Google knows this too well. Apart from the two, there are many other well-heeled and very creative advertising giants and some small but very creative nonetheless, and quite a few of them are not based in the US. CGC
