Ericsson ignored the growth of automatic telephony in the United States and concentrated on manual exchange designs. Their first dial telephone was produced in 1921, although sales of the early automatic switching systems were slow until the equipment had proven itself on the world's markets. Telephones of this period had a simpler design and finish, and many of the early automatic desk telephones in Ericsson's catalogues were magneto styles with a dial on the front and appropriate changes to the electronics. Elaborate decals decorated the cases. World War I, the subsequent Great Depression, and the loss of its Russian assets after the Revolution slowed the company's development while sales to other countries fell by about half. The acquisition of other telecommunications companies put pressure on Ericsson's finances; in 1925, Karl Fredric Wincrantz took control of the company by acquiring most of the shares. Wincrantz was partly funded by Ivar Kreuger, an international financier. The company was renamed "Telefonaktiebolaget L M Ericsson". Kreuger started showing interest in the company, being a major owner of Wincrantz holding companies. Ericsson was saved from bankruptcy and closure with the help of banks including Stockholms Enskilda Bank (now Skandinaviska Enskilda Banken) and other Swedish investment banks controlled by the Wallenberg family, and some Swedish government backing. Marcus Wallenberg Jr. negotiated a deal with several Swedish banks to rebuild Ericsson financially. The banks gradually increased their possession of LM Ericsson "A" shares, while ITT was still the largest shareholder. In 1960, the Wallenberg family bought ITT‘s shares in Ericsson, and has since controlled the company. In the 1920s and 1930s, the world telephone markets were being organized and stabilized by many governments. The fragmented town-by-town systems serviced by small, private companies that had evolved were integrated and offered for lease to a single company. Ericsson obtained some leases, which represented further sales of equipment to the growing networks. Ericsson got almost one-third of its sales under the control of its telephone operating companies. Ericsson introduced the world's first fully automatic mobile telephone system, MTA, in 1956. It released one of the world's first hands-free speaker telephones in the 1960s. In 1954, it released the Ericofon. Ericsson crossbar switching equipment was used in telephone administrations in many countries. In 1983 the company introduced the ERIPAX suite of network products and services.
