In Bicycle terms:
The hybrid bicycle first appeared on the market in 1990. It is a cross between a road bicycle and a mountain bicycle. The hybrid bicycle has a frame geometry that is responsive like that of a road bike, but with the ruggedness, maneuverability and comfort of a mountain bike. At that time, it was indeed lighter than the mountain bicycle at 27 lbs. One of the first companies that produced this type of bicycle was Miyata with their Alumicross and Triplecross models. The Alumicross was made of bonded aluminum and the Triplecross was made of high-tensile steel with lugs. other companies such as Cannondale and Mongoose followed the trend. Now known as the city bicycle, its presence has not died. Here are its general specifications to differentiate it from other types of bicycles:

Hybrid Specs.:
Frame - steel or aluminum
Components - Shimano/SRAM mountain grouppos
brakes - cantilever, "V" brake or disc brakes
pedals - usually flat pedals to accomodate normal sneakers
drivetrain - 21 + speed (w/ 3-ring chainrings)
Handlebars - flat, mountain bike style
Saddle - usually mountain style with extra padding
Wheels and tyres - 700C x 30 to 35

In advertising, a hybrid (also called a PBTI, or 'Pod-Based Tie-In', which is unweildy as all hell as a name) is a particular kind of television spot - the most common kinds are designed to appeal to the show currently being aired and to offer incentives to the viewer. For instance:

You're watching What Not to Wear. During a commercial break, one of the stars from the show appears and offers fashion advice to a confused-looking woman in a baseball cap. Stacy, the star, advises her quarry to try this new conditioner from, say,Herbal Essences, to eliminate friz or something. After Stacy is enthusiastically thanked by her victim, an announcer states that even more style tips can be found at the What Not to Wear website, and offers a URL to the same.

Tacky, right? But it works, and works well. Herbal Essences might not get the return that they want, but TLC gets website stats from every visitor and can (crudely) measure engagement by measuring the peak in site traffic when the hybrid airs. And, having been sponsored (and paid for, natch) by Herbal Essences, TLC might even make money in the deal (though usually not), so it's all good.

These particular ads are called 'hybrids' because, starring recognizable facets of the show as they do, they essentially advertise two different products (a consumable and a program) in the same commercial, blurring the traditional line between content and advertising. They also (usually) contain something called a 'call to action' - an appeal to the viewers to actually do something, in this case to log onto a web site.

A hybrid graph, in mathematics, is a graph with multiple rules for x. It usually results in an irregularly-shaped graph, sometimes with an open or closed circle, both indicating discontinuity.

A typical hybrid graph, and its corresponding rule, would look like:

      | x if x<-1
f(x)=-| 1 if -1<x<1
      |_-x if x>1

           -1 |  1
          /   |   \
         /    |    \
        /     |     \
       /      |      \
      /       |       \

The graph can be differentiated at all points except those where there is discontinuity. For this hybrid:

  • d/dx=1 if x<-1
  • d/dx=0 if -1<x<1
  • d/dx=-1 if x>1

Which means that the following is a graph of d/dx for this particular hybrid:

-----------o  |1
          -1  |  1
            -1|  o----------   

Examples of other hybrid functions include the absolute value, or modulus, function (where y=√x2, xεR) or the greatest integer function.

Hybrids commonly have no set rule, but are found on statistical graphs, such as stock exchange graphs.
