Who invented sprite stretching?

The history of sideborder sprites or $D011 based effects is pretty much known, but what about sprite stretching? I tried to find out the first demo who used it and it is not as easy as it seems: All the early 1988 demos which I thought that they used sprite stretching used normal multiplexing like used in ESCOS for example (I am talking about these "rasterbars + huge spritescroll + samples parts).

The first demo I found which had real sprite stretching was "Cocktail" from Triad (Feb 1989). Any earlier examples?

IMHO Blackmail were the first with a real FLI picture. The technique itself was a little bit older then.

Of course they were, no one has said anything else. But BF was first with the FLI-routine but used it to fake rastersplits instead.

for LINECRUNCHING I would give the credit to:

OMEGA MAN/TCS

Just look at Star Paws (Releasedate 18 July 1987)

The Title-Picture-Routine is the first kind of LINECRUNCHING I've ever seen. Before Star Paws he used a normal FLD and the LINECRUNCHING-Routine was improved later with better raster-effect and no flicker in the right border.

It has no compensate routine and definately looks like an accidently discovered effect BUT happened over 12 months earlier than the horizon routine.

I myself have first seen it in 1987 used on Centurions (Rular Game!)

for FPP I'm personally not sure who was first but definately
CREST made an FPP-Routine earlier:

Blow Job 3

the release date [20.04.1989] is to be seen on the screenshot!
(and that date is earlier than [26.06.1989])

Should one differ a (simple) logo stretcher from a full blown FPP with truly selectable gfx lines per raster line or not?

The techniques are ofcourse almost the same but still...

@jackasser: are you kidding me?
fpp and stretching are complete the same technique! or do you want to count peas... should we credit paradize for the first $d011-based logo-rotator? its still the same technique...
we are talking about vic-effects, not different sinustable-based fillings of the $d018-values... but maybe i'm wrong?

...on the topic of "who did what effect first": I think the new C64 codebase wiki would be the right place for an article about world records and world firsts:

If someone feel like it. Please add stuff to the "wanted" article right here (just click the link to create the page):

From memory it's just a split in the vertical expansion register, not a stretcher as such...?

Hmm, wasn't the game DropZone the first thing with an FPP?
