Airtel is expanding internationally with a presence in 21 countries in Asia and Africa. As technology shifts to 3G, Airtel's business model will also change. Airtel uses celebrities in their advertising and conducted market research which found that red is still a popular color among consumers. To connect with consumers, Airtel has launched branded buses and train wraps. They are also holding an online contest called "The Name Game" to get consumer input on their new logo. Airtel's arrival in India in 1995 helped launch telephony in the country and their branding expertise has made them a popular brand.
