This is sad. People really need to grow up when it comes to sex and nudity.
Heres an idea.
Have separate sections of the app store. One for 18+, and one for kids. The child access is controlled using parental controls. By default, anyone under the age of 13 can only access the child area. Parental controls can allow access to other areas but NOT the 18+ section. Anyone 13 and up can access "teen" appropriate apps, with other apps being accessible only if the parent allows but, again, NOT the 18+ section. The 18+ section is accessible only by adult accounts with verified credit cards, since modern day credit cards (even prepaid ones) require all sorts of personal information at sign up/activation.
Heres another idea.
Parents? Do your job and be a parent. Raise your kid right and teach them about sex properly. That is, after all, what you're
supposed to be doing. If you shelter your child from everything their entire life, then they're going to grow up and do stupid things when it comes to sex, drugs, etc.
So, I say again, DO YOUR JOB.
Apple needs to take a lesson from history - Porn is the major driving factor behind nearly every media format's success. VHS vs Beta. DVD vs LD. BluRay VS HDDVD. Which side did the Porn industry take? Which side won out?
VHS beat Beta because it was years before Beta tapes could hold an entire movie. VHS originally had the capacity to hold a 2 hour film, while Beta was roughly half that. On top of that, Sony didn't want to license Beta technology. Sony wanted Beta players to be Sony only, while JVC licensed VHS to everyone. By the time Sony agreed to license and had increased Beta capacity, it was too late.
DVD versus Laserdisc? Laserdisc was already 19 years old when DVD was introduced. Laserdisc was never anything more than a niche format due to the format limitations. Some LD movies were "4 sided" meaning you had 2 discs that had to be flipped over twice each. Can you imagine getting up every 30 minutes to either flip a disc or switch sides? Thats why LD was only ever a niche format.
When DVD came out it had higher resolution, higher bit-rate digital audio that was standard and not added on to the format, it was significantly smaller, and it brought with it a whole host of advantages.
There never was a DVD versus LD battle. DVD was more of the final nail in the LD coffin than anything else.
Blu-ray and HD DVD had nothing to do with porn either. Blu-ray "won" in the end because nobody other than Toshiba ever made an HD DVD player and blu-ray had more major studio support. Not only that, but after a rocky start, more and more people bought blu-ray players than HD DVD. HD DVD only lasted as long as it did because Toshiba didn't want to give up.
Why are divX, Xvid, WMV, and flash video so much more popular than QT and MP4?
WMV and Flash are more popular because Windows, up until Windows 7, has support for them out of the box. Flash is multi-platform and generally already installed for the user at first boot. Plus WMV is built-in to Windows starting with Windows XP. You don't have to install anything extra to watch a WMV. Same with Flash for most people. Plus, again, Flash is multi-platform. You can make the one thing in Flash and nearly everyone can view it.
DivX and Xvid were never popular outside of the pirate scene.
As far as H.264 goes, it wasn't meant to be thrown out into the wild and used immediately like DivX, Xvid, and WMV were. H.264 was designed by the same people who made MPEG-2 a spec. H.264 is meant to be used for years, if not a couple of decades, just like MPEG-2. So that means a couple of things. First, that it took a long time to get out. Remember, the spec wasn't finalized until 2005 or so. Second thing it means is that when it came out, it had some very high requirements for software playback. Only in the last few years have computers been released that can play standard definition and 720p H.264 video without a problem. 1080p is still only playable to an extent. If you want blu-ray quality 1080p video (blu-ray does use H.264), then you need to get the GPU in on the decoding process. H.264 is becoming the standard, but its taking time. These things don't happen over night. Don't forget that it took DVD almost 6 full years of being available to finally gain 51% market share and "overtake" VHS.
But as I said before, the adoption or non-adoption of any of the mentioned topics here have had nothing to do with porn. They were or were not adopted for other reasons.
