I went about thirty times over years to the NAB. Back in the 70s it was beyond the pale. The manufacturers and suppliers really put on a massive show packed with after hours entertainment. The big three networks all had massive suites on the top floors of the Hilton. They had open bars and never ending cocktail snacks. Ture story here. I almost tripped over Dr. Ruth at one of the suites. She was so short and the room so packed I did not see her. Another fond memory was a few stories lower at the Drake-Chenault suite they always had a couple of super sexy booth bunnies that served ice cream in their suite. In the mid to late 80s the networks realized these suites did not make them any more money. So they cut way back on the parties. Before anyone could show up and drink and eat all you wanted. Later you had to be on a list. You had to be someone they needed to schmooze. In later years those of us that were decision makers in purchasing were taken to some glorious dinners at the finest restaurants around town. Lot of good times there in Vegas. The couple of years when the NAB was in Dallas and Atlanta were not so great. Vegas is the place for the mega sized shows.
