Advertising is all about eyeballs and ears. The biggest advertisers have always been household names. e.g. Any television channel (e.g. BBC, CNN, ESPN, MSNBC, SiFi), any newspaper/magazine (NYT, Life, etc), all of radio, every storefront and its flyers (e.g. Safeway, Wallgreens, Costco). These are all directly or indirectly advertising companies that have been household names for the last 100+ years. The only difference now is (unlike for billboards), digital real-estate is very cheap and can be owned by a single conglomerate, rather than a decentralized group of capital holders.
