Reflecting a strong 2008 in which its sales — if not its stock price — jumped sharply, Apple AAPL this week made its first appearance in the top 100 of the Fortune 500 since Steve Jobs’ return.

Apple became a Fortune 500 company in 1983, but it fell off Fortune magazine’s list of America’s 500 largest companies (ranked by revenue) in 1995, while Jobs was running NeXT.

Apple climbed back onto the list in 2005, eight years after Jobs’ return. It vaulted an impressive 32 spots this year to land at No. 71, thanks in part to the declining fortunes of some of the firms that were above it, but mostly to revenues that grew 35.3% to $32.479 billion in 2008.

Other companies made larger leaps — URS Corp. URS had the biggest, jumping 185 spots to No. 264 — but they were all considerably smaller than Apple. None landed in the Fortune 100.

The Fortune 500 issue is dated May 4 but was released this week online. The big news this year is that Exxon Mobil XOM displaced Wal-Mart WMT at the No. 1 spot.

Among Apple’s largest U.S. competitors, Hewlett-Packard HPQ came in at No. 9, Dell DELL at No. 33 and Microsoft MSFT at No. 35.
