"On Aug. 27, 1976, a team led by Don Nielson, then assistant director of telecommunications at Menlo Park engineering firm SRI International, drove a specially equipped van 6½ miles south and parked at Zott’s. They ran a cable from the van’s radio to a computer set up at a picnic table out back and used the radio to connect to another computer at the SRI office and on to Boston. The Internet was born."

The internet (ARPANET, at the time) was born when the first packet was sent several years earlier, on 29 October 1969.[1]

This article seems to describe the first time that mobile equipment was used to connect to the ARPANET, which is interesting, but not the birth of the internet.

Also, a network connection on a dedicated radio link was a fun experiment to do, but it didn't make possible the widespread mobile deployment of the internet we have today. That required the building of a cellular phone network capable of sending data at high speeds, which happened many years later.
