The Nasdaq, home to many of the biggest tech companies in America, hit the 6,000 mark for the first time ever on Tuesday. The milestone comes more than 17 years after the Nasdaq first topped 5,000 -- way back in March 2000. Sure, not much has changed now that the Nasdaq is at 6,000 as opposed to, say, 5,970. Smartphones, online advertising, e-commerce, cloud computing and social networking are big tech trends that have helped fuel the Nasdaq's rise -- and it has continued in 2017. Big multinational tech companies outside of technology, such as Caterpillar (CAT), DuPont (DD), McDonald's (MCD) and 3M (MMM), all reported strong earnings on Tuesday.
