1.The brand of World War II
2.Golden age
Arrive from hind of World War II at the beginning of 90 time, can say the time that is Motolora flourishing. Motolora the technical advantage that in imitate wireless communication respect has any companies to cannot be likened to, and innovation gives multinomial world the first. American communication bound has a kind of current classification method to communication, divide namely for: Wired and one-way (be like closed-circuit television) , wired and two-way (like the phone) , wireless and one-way (like the radio) and wireless and two-way (like the mobile phone the phone is mixed WIFI) 4 kinds. Long-term since, till ten years before, AT&T is the king of finite communication all the time, RCA is the old of infinite and one-way communication, and the overlord of the wireless and two-way communication that Motolora is one hundred percent. We can see once upon a time, the core business of Motolora is concerned with two-way wireless communication.
1946, motolora invented car phone. Had seen Bao Jia and conspicuous act originally ” Sabrina (Long Feng matchs) ” the reader may be right this kind of product has impression, big company president regards as Linus in film grow an island from new York set out in the home, go up the instruction of company staff make known to lower levels that the car carries car phone to with a ha pause to Yuan Zaiman. Very regretful is, car phone is the luxury of wealthy person all the time, it has not gotten popular, was replaced by mobile phone phone. After 12 years, motolora invented the interphone that is based on a car, it is in the United States to be used extensively with all sorts of transport companies by company of police, taxi, be replaced by mobile phone phone till 90 time end (gave a police still using) . Be in 2000 previously of each country alarm bandit piece in, we often see this product.
Was told 1963 to Motolora is a memorable time. This year, motolora invented the color television picture tube of the first rectangle, and it made occupation standard quickly. (before this, the color television screen that RCA produces is a circle. See this picture please)
1967 year, motolora production gives chance of colour television of the first complete transistor of American, the color television previously returns some valve more or less. This issue is very large to Motolora influence, previously although Motolora is banner on the technology at the world, but product besides the radio in the car not be civil. The invention of chromatic picture tube, indicating Motolora is capable to entered civil market and turn to the key of business civil. But regretful is, the Motolora attempt in initial stage of home appliance market is very not successful, to 1974, it must sell Japanese pine next companies. Today, very few somebody knows Motolora is right the contribution of color television industry.
In 669 time, the has go up in color television failure that Motolora can experience completely, because it is banner the technology at the world is too much. To 80 time, motolora enters 10 years when develop flourishingly, its business also is expanded by wireless communication the semiconductor chip of the computer. 1979, motolora rolls out 68000 general microprocessor successfully, because it is designed compositive degree get a name for 68000 transistor (although actual and compositive degree for 70000) . Its address bus line (Address Bus) width is 24 peculiar, can manage the memory of 16 MB, accordingly it makes the first selection chip of all and small-sized machine and workstation. And the half generation after the processor of Intel of the corresponding period compares it to fall actually, 16 address width can manage latter only the memory of 64 K.
80 time, as the development that digital signal handles, appeared to handle chip to appropriative number signal (DSP) demand, this product also is born because of carry. Heart state apparatus (TI) , AT&T and Motolora are at the beginning of 80 time rolled out TSM early or late, DSP and M56K product of 3 old series, this market grows such fast, brought a new golden ore deposit to Motolora. Today, the chip of mobile phone core that adds periphery communication for core with DSP remains whole world sales volume the biggest, most profitable semiconductor chip (because every mobile phone is medium,must have a such core) .
Of course, the contribution with the largest to the world Motolora is its civil beehive type in the invention at the beginning of 80 time mobile telephone, namely inchoate saying hand-hold portable telephone, the mobile phone that says now. Everybody is accepted the invention company that Motolora is communication of current mobile phone, the mobile phone that although AT&T claims,its cordless telephone compares Motolora is early, but everybody knows cordless telephone and mobile phone phone is two different matters. As a result of AT&T take root at wired communication, not self-conscious can inimical wireless communication. When the mobile telephone just started, AT&T predicts to 2000 the whole world does not exceed million user, this estimation is compared the actual amount when 2000 is 100 times smaller later. So, AT&T nature won’t put the emphasis on mobile. And Motolora is antipodal, it has impossibly on wired communication as, go up in mobile from however stake, lead and drove the tide of mobile.
Arrive at the beginning of 90 time, motolora is handled in signal of mobile, number and computer processor 3 domains are the Player with the most powerful technology on the world. More commendable is, its product fame is wonderful. The product that I contact Motolora the earliest is in 80 time end, the friend of a few custom introduces their Motolora interphone to me. The colleague that goes up with the bank in the big steamer hold that those interphone can surround in iron and steel communicates, this is impracticable of any other and congener product. 1990 year, the turnover of Motolora exceeds one billion four hundred and ten million and sixty-five thousand four hundred and eight dollars, IBM and AT&T are next to in IT company. If Motolora can sweep the deck 3 big markets, it will be today undoubtedly the biggest IT company on the world. Although it can forestall among them, also be gigantic without bully company. Very regretful, it also was not done good, the technical tide that the leader of this communication revolution is lifted by oneself fell into disuse. Does the reason where?
