The service resembles that of YouTube, whereby a viewer can watch videos for free. However viewers can add "Early Access" at a monthly fee to their account, which allows them to view videos a minimum of 72 hours before the video is released to the general public. Vessel has since created mobile applications for iOS and Android devices which optimizes the videos for mobile viewing.
The idea behind the site was that creators would be able to gain more revenue from their videos than on YouTube due to the subscription fee as well as advertisements.
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick.
The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it both to move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane.
Forms of derricks are commonly found aboard ships and at docking facilities. Some large derricks are mounted on dedicated vessels, and known as floating derricks and sheerlegs.
The term derrick is also applied to the framework supporting a drilling apparatus in an oil rig.
Derrick is a German TV crime series produced between 1974 and 1998 about Detective Chief Inspector (Oberinspektor) Stephan Derrick (Horst Tappert) and his loyal assistant, Inspector (Kriminalhauptmeister) Harry Klein (Fritz Wepper), who solve murder cases in Munich and surroundings (with three unsolved cases in total). It was produced by Telenova Film und Fernsehproduktion in association with ZDF, ORF and SRG
On 2 May 2013 ZDF announced it would no longer carry reruns of the show, after it emerged that Tappert had been untruthful in discussing his service in the Waffen-SS in World War II.
All 281 60-minute episodes were written by veteran screenwriter Herbert Reinecker and produced by Helmut Ringelmann. As a rule, new Derrick episodes were broadcast on Friday night at 20:15. The series received enormous popularity and was aired in more than 100 countries worldwide.
The series' discontinuation in October 1998 came as Horst Tappert had reached the age limit he had set himself. Horst Tappert is the only German actor who has ever had fan clubs abroad including the Netherlands and France.
