At that time, many evening news agencies conducted "pulse polls" for $.50 per call charges and displayed results on television.One early use was by Saturday Night Live producers for the sketch "Larry the Lobster", featuring Eddie Murphy. AT&T and the producers of SNL split the profits of nearly 0,000.A call to either one of these numbers can result in a high per-minute or per-call charge.
In some jurisdictions, telephone companies are required by law to offer such blocking.
Numbers with the 900 area code were those which were expected to have a huge number of potential callers, and the 900 area code was screened at the local level to allow only a certain number of the callers in each area to access the nationwide long distance network for reaching the destination number.
Also, the early incarnation of 900 was not billed at premium-rate charges, but rather at regular long distance charges based on the time of day and day of week that the call was placed.
Therefore, in contrast to North America where customer service numbers are typically free of charge to the caller, consumers in Europe often used to pay a premium above the cost of a normal telephone call.
The EU Consumer Rights Directive 2011/EU/83 came into force on 13 June 2014. Implementation detail, and hence the level of success in achieving this aim, varies considerably from country to country.
