LAS VEGAS (AP) — CES is the place startups and established tech giants alike go to unveil their latest tech gizmos.

So what are 181-year-old stalwarts like John Deere DE and Procter & Gamble PG doing at the world’s largest technology show?

These two companies are first-time exhibitors, along with missile-maker Raytheon RTN, outdoorsy retailer The North Face and the 115-year-old motorcycling icon Harley-Davidson HOG. John Deere, for instance, has computer-vision technology to track the quality of grain coming into a combine harvester so that its kernel-separating settings can be adjusted automatically.

The four-day show opens in Las Vegas on Tuesday.

Gary Shapiro, CEO of CES organizer Consumer Technology Association, says every company is a technology company these days.
