The Super Bowl is on a different network each year.
The World Series used to be on NBC, and then moved around to ABC and CBS before finding a home at Fox.
The NHL and NBA playoffs have moved around, too, and the NCAA's Final Four is now even on cable.
Things have changed a lot on the major sports TV landscape over the past 50 years, but there's one thing that has stayed the same — the Indianapolis 500 on ABC.
The "Greatest Spectacle in Racing" being on the alphabet-starting network is one of the many traditions associated with one of the most tradition-rich events in sports.
"Fifty years on ABC. … for me, that starts with a 'Wow'," said Rich Feinberg, ESPN vice president in charge of motor sports production, during a teleconference this week. "My personal memories of the Indy 500 and ABC's coverage of it date back to when I was a kid. Memorial Day weekends with my family … appointment viewing. Those days it was on a tape delay at night. To see it come around a 50-year anniversary is just amazing."
Feinberg calls it a "cherished assignment that everybody embraces."
"Our goal is quite simple, and that's to uphold the tradition of excellence in coverage that's been established by our ABC colleagues over the past 49 years," he said.
Allen Bestwick, better known for ABC/ESPN's NASCAR coverage, will be the lap-by-lap announcer for the first time with Eddie Cheever and Scott Goodyear returning as analysts.
Even with the Coca-Cola 600 NASCAR race to follow on Fox later in the day, this is IndyCar's one day to shine; it's open-wheel racing's Super Bowl. And it's a day to embrace the past as well as cast a hopeful eye toward the future.
"I dreamed about it as a child when I was living in Italy, and I heard it on the radio," Cheever said. "I was lucky to come here and race. I was lucky enough to win it. Now I'm going to be sitting in the booth with two friends calling the 50th anniversary of ABC calling the Indy 500. I don't know how it could be any better than that."
Here in the Lehigh Valley, it could only be better if one of our two Nazareth natives — Marco Andretti or Sage Karam — takes the checkered flag.
A win by either would make it one of the biggest days in local sports history.
Obviously, Andretti, who narrowly missed winning his first 500 in 2007, has the better shot.
ABC's cameras as well as Bestwick, Cheever and Goodyear will be keeping a close eye on Andretti all day. He's starting sixth and usually is in contention.
"He is always a threat to win," Cheever said. "It's his family's team. He has been very quick. His rookie year at Indy was unbelievable. He lost by the smallest of margins. He is unfortunate in that he has some incredibly talented teammates and he's really going to be judged not so much by the fact that he wins or doesn't win, but how he compares with his teammates. That's a tall order."
Goodyear, who had his share of hard luck at the Brickyard with second-place finishes in 1992 and 1997 and was disqualified in 1995 even after he crossed the finish line, has empathy for Andretti.
"It weighs on you when you come back here to the Indianapolis 500," he said. "For him, I'm sure he thinks about it. I talked to him about it. He said 'No, it's behind me, I don't think about it too much.' But you do.
"I always looked at it like you'll get another chance. [Winning this race] is the reason you're living, breathing and racing. Your last name is Andretti, and there's pressure on a third-generation driver. I would love to see him win. It would be great for him, his family, and our sport to have Andretti win again."
As for 19-year-old Karam, Goodyear called him a nice young man who should not be in a rush.
"Times have changed, because at 19, I was just finishing karting and about ready to take my first day of Formula Ford school," Goodyear said. "They almost have harnessed him back a little bit because the team says he is very eager to get going and is trying to get so much accomplished in a short amount of time.
"As a rookie here, you can be very fast. But 500 miles is such a long, long time on the racetrack. I always broke it up into five 100-mile races. You have to get yourself through it and not rush."
Cheever agreed, saying: "Talent, youth and energy are wonderful things to have, but don't really fit in that well with how you approach the Indy 500. Here you have to have an enormous amount of patience. You have to be willing to listen to the pits, pick yourself up from a bad stint with the tires not working or you have some sort of problem. It will be a great testament to his ability if he can finish the 500."
The NBA's Western Conference finals are up 31 percent in the ratings on TNT and one of the reasons may be the lively banter between Charles Barkley, Kenny Smith, Shaquille O'Neal and Ernie Johnson on the pregame, halftime and postgame coverage.
Barkley's always got something going on, including his friendly feud with the women of San Antonio. A couple of pretty ladies responded by wearing "Barkley Don't Know" T-shirts.
Barkley fired back by saying the good lookers must have been imported from Dallas.
ESPN paid special attention to Dodgers outfielder Yasiel Puig with an iso cam during its Dodgers-Mets broadcast on Wednesday. ESPN adopted Puig as the next athlete to overexpose and since baseball lacks compelling figures these days, Puig seems ripe for the hype.
Also on ESPN's "First Take," Skip Bayless continues to annoy with how he adopts certain athletes and teams as his favorites.
He must have said "My San Antonio Spurs" 10 times during a two-minute segment the other day. Two key tenets of journalism are no cheering in the press box and redundancy, and Bayless violates both all of the time although he may consider himself to be more of an entertainer than journalist.
KEITH'S CAN'T MISS … The Indy 500 is one of those events where the buildup often beats the actual event. Forty-five years after his grandfather Mario had his win, can Marco Andretti end the family curse? ABC's coverage begins at 11 a.m. on Sunday.Copyright © 2015, The Baltimore Sun
