Question: When did cable cars start in the city where the Internet Archive is headquartered?

full_context: Document 1: Wayback Machine: In October 2013, the company announced the "Save a Page" feature which allows any Internet user to archive the contents of a URL. This became a threat of abuse by the service for hosting malicious binaries.
Document 2: London: London's first and only cable car, known as the Emirates Air Line, opened in June 2012. Crossing the River Thames, linking Greenwich Peninsula and the Royal Docks in the east of the city, the cable car is integrated with London's Oyster Card ticketing system, although special fares are charged. Costing £60 million to build, it carries over 3,500 passengers every day, although this is very much lower than its capacity. Similar to the Santander Cycles bike hire scheme, the cable car is sponsored in a 10-year deal by the airline Emirates.
Document 3: Wayback Machine: The Wayback Machine is a digital archive of the World Wide Web and other information on the Internet created by the Internet Archive, a nonprofit organization, based in San Francisco, California, United States. It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet. The service enables users to see archived versions of web pages across time, which the archive calls a "three dimensional index."
Document 4: Wayback Machine: In Europe the Wayback Machine could be interpreted as violating copyright laws. Only the content creator can decide where their content is published or duplicated, so the Archive would have to delete pages from its system upon request of the creator. The exclusion policies for the Wayback Machine may be found in the FAQ section of the site. The Wayback Machine also retroactively respects robots.txt files, i.e., pages that currently are blocked to robots on the live web temporarily will be made unavailable from the archives as well.
Document 5: Fisherman's Wharf, San Francisco: Fisherman's Wharf is a neighborhood and popular tourist attraction in San Francisco, California. It roughly encompasses the northern waterfront area of San Francisco from Ghirardelli Square or Van Ness Avenue east to Pier 35 or Kearny Street. The F Market streetcar runs through the area, the Powell-Hyde cable car lines runs to Aquatic Park, at the edge of Fisherman's Wharf, and the Powell-Mason cable car line runs a few blocks away.
Document 6: List of Barcelona Metro stations: Lines L1, L2, L3, L4, L5, L9, L10, L11 and the Funicular de Montjuïc are administered by Transports Metropolitans de Barcelona (TMB), the city's transit company. Lines L6, L7, L8 and L12 are in origin commuter train services with extended frequency and integrated into the metro network, numbered as such, and run by the public Ferrocarrils de la Generalitat de Catalunya (FGC), which belongs to the Catalan government or Generalitat de Catalunya.
Document 7: San Diego: San Diego is served by the San Diego Trolley light rail system, by the SDMTS bus system, and by Coaster and Amtrak Pacific Surfliner commuter rail; northern San Diego county is also served by the Sprinter light rail line. The Trolley primarily serves downtown and surrounding urban communities, Mission Valley, east county, and coastal south bay. A planned Mid-Coast extension of the Trolley will operate from Old Town to University City and the University of California, San Diego along the I-5 Freeway, with planned operation by 2018. The Amtrak and Coaster trains currently run along the coastline and connect San Diego with Los Angeles, Orange County, Riverside, San Bernardino, and Ventura via Metrolink and the Pacific Surfliner. There are two Amtrak stations in San Diego, in Old Town and the Santa Fe Depot downtown. San Diego transit information about public transportation and commuting is available on the Web and by dialing "511" from any phone in the area.
Document 8: Wayback Machine: In 1996 Brewster Kahle, with Bruce Gilliat, developed software to crawl and download all publicly accessible World Wide Web pages, the Gopher hierarchy, the Netnews (Usenet) bulletin board system, and downloadable software. The information collected by these "crawlers" does not include all the information available on the Internet, since much of the data is restricted by the publisher or stored in databases that are not accessible. These "crawlers" also respect the robots exclusion standard for websites whose owners opt for them not to appear in search results or be cached. To overcome inconsistencies in partially cached web sites, Archive-It.org was developed in 2005 by the Internet Archive as a means of allowing institutions and content creators to voluntarily harvest and preserve collections of digital content, and create digital archives.
Document 9: Wayback Machine: Snapshots usually become available more than six months after they are archived or, in some cases, even later; it can take twenty-four months or longer.  The frequency of snapshots is variable, so not all tracked web site updates are recorded. Sometimes there are intervals of several weeks or years between snapshots.
Document 10: Wayback Machine: On April 25, 2007, Internet Archive and Suzanne Shell jointly announced the settlement of their lawsuit. The Internet Archive said it "...has no interest in including materials in the Wayback Machine of persons who do not wish to have their Web content archived. We recognize that Ms. Shell has a valid and enforceable copyright in her Web site and we regret that the inclusion of her Web site in the Wayback Machine resulted in this litigation." Shell said, "I respect the historical value of Internet Archive's goal. I never intended to interfere with that goal nor cause it any harm."
Document 11: Wayback Machine: In a 2009 case, Netbula, LLC v. Chordiant Software Inc., defendant Chordiant filed a motion to compel Netbula to disable the robots.txt file on its web site that was causing the Wayback Machine to retroactively remove access to previous versions of pages it had archived from Nebula's site, pages that Chordiant believed would support its case.

Document 13: Wayback Machine: In late 2002, the Internet Archive removed various sites that were critical of Scientology from the Wayback Machine. An error message stated that this was in response to a "request by the site owner." Later, it was clarified that lawyers from the Church of Scientology had demanded the removal and that the site owners did not want their material removed.
