was an increase in usage of online DVD rental services such as Netflix. DVDs, and subsequently Blu-ray Discs, replaced VCR technology as the common standard in homes and at video stores, although inexpensive VCRs and videocassettes could still be found at some thrift stores and discount stores. Vehicles and energy There were major advances in hybrid vehicles such as the Toyota Prius, Ford Escape, and the Honda Insight. Many more computers and other technologies were incorporated into vehicles, such as Xenon HID headlights, GPS, DVD players, self-diagnosing systems, advanced pre-collision safety systems, memory systems for car settings, back-up sensors and cameras, in-car media systems, MP3 player compatibility, USB drive compatibility, self-parking systems, keyless start and entry, satellite radio, voice-activation, cellphone connectivity, adaptive headlights, HUD (Head-Up-Display), infrared cameras, and Onstar (on GM models). There was greater interest in future energy development due to global warming and the potential scenario of peak oil, even though these problems had been known about for decades. Photovoltaics increased in popularity and decreased in cost as a result of increased public interest and generous public subsidies. Communications The popularity of mobile phones and text messaging surged in the 2000s decade in the Western world. The advent of text messaging made possible new forms of interaction that were not possible before, resulting in numerous boons such as the ability to receive information on the move. Nevertheless, it also led to negative social implications such as Text "bullying" and the rise of traffic collisions caused by drivers who were distracted as they were texting while driving. Due to the major success of broadband Internet connections, Voice over IP (VoIP) began to gain popularity as a replacement for traditional telephone lines. Major telecommunications carriers began converting their networks from TDM to VoIP. Unusually for a development heralded by science fiction, videophones were cheap and abundant, yet even by mid-decade, they had not received much attention, perhaps due to the high cost of video calls relative to ordinary calls. Mobile phones adopted features such as Internet access, PDA functions, running software applications, video calling, cameras and video recording, and music and video playback as standard. Higher end smartphones continue to offer extra features such as GPS and Wireless. Due to improvements in mobile phone displays and memories, most mobile phone carriers offered video viewing services, internet services, and some offered full music downloads, such as Sprint in 2005 and more
