What is the difference between "Performance", "Action Art", "Installation Art" and Video Art?

When the artist or the body of the artist is in focus, so the acting is part of the artwork, it's a performance. When the artist isn't visible but it's still about people and when it's that fast changing in time that you can see the "Beginning" and then "End", than it's "Action Art" (Happaning is kind of outsourced - not directed by a single artist but by many). Installation is when you can't see it "changing" in time, so it looks always the same, or can be at least restored, and when it's about objects.

However even still some installations like "My Breath rests here" ("Hier ruht mein Atem") have some performance character (at least in the creation phase), but than again not really, because than "the painting of a painting" could be also a performance, so it's more about the focus.

A recorded and shown as a video performance, without real life viewer and the interaction with the viewer like "The 30 € truth" or "Crying for this Video" for example is a video. (Definition by Bieniek)

"Sponsored By", a performance in the city center of Braunschweig with seven shopping carts with advertising lettering and a cross hanging around them. It was only one month after Bieniek started to study art in the city of Braunschweig.

"Sponsored By", 1996 Performance art by Sebastian Bieniek (B1EN1EK). The artist as Jesus sponsored by big companies.

Naked in cling film and carrying a cross, Sebastian Bieniek pulled seven shopping trolleys through the inner city of Braunschweig in his first performance in 1996. Past shopping malls, shops, cafes and shop window displays. On the last shopping cart and thus the end of this procession, a sign was attached that read: "Sponsored by". There were logos of large companies printed below it.

With this allusion to Jesus Christ, the artist wanted on the one hand to demonstrate consumer criticism and on the other hand to criticize the influence of commercial enterprises on areas in which, in his opinion, the economy should not be at home.
