So lucrative a TV commodity have the Olympic Games become, that it is not surprising producers are already moving to exploit them even further.

MCA-TV is first out of the starting block with its syndicated series about the Summer '84 Games, "The Road to Los Angeles," which went into pre- production in May. Four crews are working in the US and one abroad on the 30 one-hour shows scheduled to premiere in January. An additional 30 hours will begin in January, 1984.

"The Road to Los Angeles" will profile America's finest Olympic athletes, comparing our training procedures to those of the leading foreign competitors. Each segment will feature five or six athletes discussing the adjustments in their personal lives and demonstrating pre-Olympic training and competition.

Programs will be hosted by leading American sports figures who can offer first- hand knowledge of each segment's special theme, such as style, discipline or coaching.

ABC has also caught Olympic fever. With $450 million already invested in rights and production costs, it will televise a record 207.5 hours from the 1984 Summer Olympics, most of them live.

More than 2.5 billion people worldwide are expected to tune in the Olympics, including at least 150 million Americans. Athletes from 150 nations will be competing, including China, which is participating in the games for the first time since 1932.

The Games will no longer be male dominated: Almost half the coverage scheduled will focus on women's events.

And meanwhile, everything seems on schedule at the site of the 1984 Winter Olympics in Sarajevo, Yugoslavia, from which ABC will broadcast 65 hours.
