Dish Network has been the subject of a number of criticisms relating to management of advertising, disclosure of fees, telemarketing, employee rights and programming disputes; a number of which resulted in lawsuits. In the early 2000s, Dish Network received criticism regarding controversial technology and carriage disputes with programming providers. Most notably, when the Hopper digital video recorder provided an easy way for viewers to watch certain programming without commercials, major networks sued Dish Network.
