The idea of creating an on-field marker to help TV viewers identify 1st down distances
was conceived and patented in 1978 by David W. Crain,who presented the concept
to Roone Arledge[7] and Roger Goodman[8] of ABC News and Sports and to the CBS
Technology Center.At the time, both decided the broadcast industry was not
ready to use Crain's invention. In 1998, ESPN Programmer Gary Morgenstern and others
,revived the idea. ESPN's NFL Coordinating Producer, Fred Gaudelli was tasked with
overseeing an implementation for their network. The 1st & Ten line was first broadcast
by Sportvision, a private company, during ESPN's coverage of a Bengals-Ravens game on
September 27, 1998. A few weeks later, on Thanksgiving Day in 1998 (October 12),
Princeton Video Image (PVI) aired their version of the virtual yellow down line on a
CBS broadcast of a Pittsburgh Steelers–Detroit Lions game.Four years later,
SportsMEDIA introduced a third version during NBC coverage of a Notre Dame game.
The rivalry between PVI and Sportvision began with a collaboration. In July 1995 PVI
had successfully used their L-VIS (Live Video Insertion System) match moving technology
to broadcast virtual advertising behind the home plate on a local broadcast of a
Trenton Thunder baseball game in Trenton, New Jersey. In January 1996, Roy Rosser,
Director of Special Projects at PVI saw SportsVision's FoxTrax puck on the broadcast
of the 1996 NHL All-Star Game and realized that a combination of L-VIS and FoxTrax
would allow virtual insertions in a wider range of situations than either could do
on their own, given the then power of affordable computers. He contacted Stan Honey,
CTO at Sportsvision, and the two companies undertook a joint demonstration of their
combined technologies during the 1996 World Series between the Atlanta Braves and
the New York Yankees at the Atlanta Fulton County Stadium. The test was not a success
and the two companies parted ways, each developing complementary systems that were
eventually used to broadcast Sportsvision's "First and Ten" line and PVI's "Yellow
Down Line". In October 1999, SportVision sued PVI alleging that PVI's virtual
signage, first down line, and other products infringed Fox/Sportvision patents.
In August 2001, PVI counterclaimed against Sportvision in the Federal Court action,
alleging that Sportvision's virtual strike zone and virtual signage products
infringed a PVI patent. In 2002, the companies settled the law suits out of court
through a cross-licensing deal.
