I agree, many companies do not care. I know a guy who does online advertising for a Middle Eastern airline. Many of his campaigns do not work out, he's blown large budgets due to simple mistakes and no one cares, and he's given a budget that he just _has_ to spend. However, campaigns do work; many of the viral content you see has been carefully engineered and propogated by clever ad agencies.

I have to disagree on your opinion about mobiles. Mobile e-commerce is very intuitive and fast for many users (see Kim Kardashian). Consuming and sharing of media on mobile has led to clickbait and some brands have earned big money from that (see Buzzfeed). People scroll through mobiles addictively, and the invention of the "feed" by Zuckerburg combined with targeted advertising has users doing exactly what ad companies have want them to do, whether it be sharing, consuming, or purchasing.
