WORTH NOTING ON TV

FRIDAY

The Tonight Show (NBC, 11:30 p.m.-12:30 a.m.): The last "Her-r-r-e's Johnny," after 30 years. Can it really be? (See column on opposite page). SUNDAY

The Indy 500 (ABC, 11 a.m.-3:30 p.m., ET): The 76th Indianapolis 500, the world's premier auto race, is covered live from the Indianapolis Motor Speedway. Four-time winner Rick Mears is back to defend his title against seven former champions in a field of 33 drivers. Never say this in front of a hard-core fan, but four and a half hours is a lot of auto racing to watch - even for the Indy - and viewers can, if they choose, keep up with it in snatches. But when you are watching, you'll see speeds close to 225 mph. The winner takes home about $1 million. Not bad for a Sunday spin. TUESDAY

Made in America (PBS, 8-10 p.m.): When economists refer to the "global economy," what they are really talking about is Americans out of work and American families whose kids could face bleak "service industry" jobs (read "McDonalds") in the years ahead. This two-parter focuses on four industries - electronics, automotive, clothing, and commercial-aircraft manufacturing - as it explores the issue of American competitiveness in making goods for the international market. What must Americans do to be success ful? What are the myths about this world market and what are the facts? Harvard University political economist and author Robert B. Reich is the knowledgeable host guiding viewers toward some answers. (Part 2 airs Wednesday night.)
