1. "Service Provider", used in "escort review" forums to refer to a working girl, painted lady, lady of the night...
2> "Standard
Play", the shortest runtime on media formats which offer a choice between SP (standard
play),
LP (long
play), EP (extended play). For instance , the VHS video home system had T120 as the standard videocassette, which held two hours (120 minutes) of SDTV on SP, four hours on
LP, six hours on EP. The lowest denominator (supported from the first VHS VCR onward) was SP, which forced some particularly long feature films (like
Mario Puzo's "Godfather" series) onto a second cassette.
3. "Service Pack" in software version numbering; "WinXP SP3" was Windows XP, Service Pack 3, for example.
