Name comes from Harald Bluetooth, king of Denmark in the late 900s

There are lots of different ways that electronic devices can connect to one another--Component cables, Electrical wires, Ethernet cables, WiFi, Infrared signals…

Bluetooth is essentially a networking standard that works at two levels:

It provides agreement at the physical level -- Bluetooth is a radio-frequency standard;

AND, it provides agreement at the protocol level, where products have to agree on when bits are sent, how many will be sent at a time, and how the parties in a conversation can be sure that the message received is the same as the message sent. (cell phone, GPS, PDA--Starfield example)

Delivery of video to cellular phones is becoming more widespread… voice / data … and

Verizon’s V-Cast service (3G EV-DO) MobiTV service.

Both use the cellular network to deliver the content.

New service and technology, MediaFlo, developed by Qualcomm, uses part of the television broadcasting spectrum (channel 55) to send multi-media content to mobile phones (as noted before).

Allows wireless carriers to offer video content without taking up much needed bandwidth in their cellular network.

“Survey Says Broadband To Lag TV in 2012. Forget About It” by: Will Richmond

This piece in recent Hollywood Reporter about a newly-released survey ("Broadband Won't Overtake TV, Execs Say") caught my eye because it continues a highly speculative, and largely irrelevant debate pervasive throughout the industry about future video consumption patterns.

Why's the debate highly speculative? Because truly, none of us has any idea how people will consume video in 2012. There are just too many variables and too many unknowns to make an accurate prediction.BUT – ‘mobile media’ – ‘Internet TV’

Here's a point of comparison: let's say 5 years ago, in 2002, you were asked what

percentage of Americans would consume broadband video in a given month?

How many (or few!) of us would have predicted a whopping 75%? (the correct answer according to comScore in July '07).

Better yet, how many of us would have guessed that over 25% of this consumption would be at just one site (YouTube) - a site that didn't even exist in 2002?

Given these examples, who's to predict what 2012 will bring?
