Но ведь это ты путаешь. Именно рекламой дисков с аниме показы аниме по ТВ и являются

Начни ликбез со статьи Late night anime в википедии, там такое написано:

"In most cases, a production committee (a group of several related companies) buys a time slot from a TV station. This process is known as brokered programming, and is similar to how infomercials are broadcast. Therefore, unlike ordinary programs, production companies are sponsoring companies as well. This way, TV stations can fill the time slots with low viewership, while production companies can advertise their products (anime DVDs) at a lower cost."
