Dish Network on Monday launched Dish Media Sales, an automated marketplace that will let advertisers buy TV spots the same way they can buy ads online. With the initiative, Dish will give advertisers the ability to purchase targeted, linear TV ads, impression by impression, using real-time bidding technology — similar to the way online ads are purchased. “Our addressable technology offers an improved viewer experience as we deliver ads with greater relevance to a consumer’s needs,” said Adam Gaynor, vice president of Dish media sales.
