While certainly the most prevalent and cheap, the most annoying ads are not AR spam, they're Trideo ads. While significantly more expensive, they're generally considered more effective since AR-spam can quickly be muted by a simple adjustment to a commlink's firewall. Trid ads on the other hand are annoyingly persistent and frequently cause people to get quite frustrated with their commlink trying to shut them off, not realizing that the offending ad is not being routed through the commlink at all, but instead through real space.
The annoying nature and perceived audacity of these types of ads is so prevalent that the phenomenon has created its own meme:
{AR user taps his commlink to mute ad but still sees ad... AR user taps angrily on commlink to mute ad but still sees ad.... AR user goes out and buys new Fairlight commlink but still sees ad... AR user smashes commlink repeatedly with hammer but still sees ad........ AR user gouges eyes out with an icepick. Does not see ad anymore.... Frag you TridAd, I win.}
Transapparency - The property of an object that allows it to be seen despite the presence of intervening objects. Frequently used in safety applications such as making the ARO of a vehicle apparent even when the physical vehicle is in a blind spot or otherwise obscured.
Because of the transapparency of certain AROs and the personalizing features of certain AR rendering engines, many feel that the AR experience is an isolating one, at least compared to a group viewing of a common image such as in trideo or a live performance. For that reason sports bars in particular will often make significant capital investments into high end trideo projectors to create that common viewing experience for their patrons thus helping to engender a team spirit and community feel as patrons feed off each other's excitement (or disappointment) more easily.
On a similar note, trideo is often used in applications where a very specific experience is desired, such as in a high fashion applications where the designer doesn't want the rendering of their "art" to be altered by personal filters or mangled by someones cheap DNI connection.
