Getting a bigger audience to attract larger advertisers is what pushed newspapers, radios, television channels and finally web services to become behemoths.
While there are certainly economies of scale that may allow others to do better anyone can engage in some sort of advertising, guerilla marketing is definetly a decentralized advertising tactic.
If monopoly is defined solely in terms of dominance it is ironically possible for there to be a decentralized monopoly as technically anyone can enter by any means but there is one big fish in the pond. I dislike that definition of monopoly personally because a monopoly with no concrete barriers to entry feels like an absurd abuse of the term.
