Historically, the United Parcel Service, FedEx and the U.S. Postal Service have carried most of the weight of the delivery process. Now, the tech giants want in. Google announced Monday it is expanding its same-day deliveries, following Amazon’s increased development of a similar service. Conquering home delivery has been compared to achieving the “Holy Grail of e-commerce.” Disrupting the delivery process offers these tech companies a way to attain total domination of the shopping experience, and it will almost certainly be a good thing for consumers, too.

Google’s service, which been operating in San Francisco for just over a year and is now expanding to parts of New York and Los Angeles, offers expedited shipping from major stores including Target and Walgreens. In a similar fashion, trucks managed by Amazon-supervised contractors are now delivering packages to consumers in parts of San Francisco, Los Angles and New York. (Sorry, everyone else, you’re out of luck for now.)

The Postal Service, UPS and FedEx should take note. Right now, package delivery is a positive note for the cash-short USPS, so much so that it struck a deal with Amazon last fall to deliver packages on Sunday. Tech companies jumping in the delivery game probably won’t affect the main distribution players for now. It is unlikely Amazon or Google could afford to manage truck distribution in less populated areas, and increased success of e-commerce could even result in increased business for UPS and FedEx as other retailers try to ramp up their own online-delivery operations. But as Amazon and Google iron out the kinks and bring on the drones, we’re in for an exciting — and let’s hope more reliable — delivery future.
