These Stevenotes, in contrast to those presented at the large trade fairs attended by Apple in the past, were by invitation only and were attended only by a relatively small number of journalists, employees, and guests, and were called "special events" rather than keynotes. Similar Stevenotes have also been held at the Yerba Buena Center for the Arts like those for the introduction of the iPad in 2010 and Apple's "Rock and Roll" iPod event in 2009. Jobs was known for donning the same uniform in nearly every keynote since 1998.
